The Geological Unconscious had a wonderful six week run at Hypha HQ, Euston. Responding to Jason Groves’ inquiry into the mineral imaginary in his eponymous book, as well as the ‘Writing of Stones’ as proposed by writer and mineral collector Roger Caillois, the exhibition exposes the complex entanglements between the organic and the inorganic; the human and the lithic. 

Very happy to receive lots of positive feedback for my video installation Lithos Panoptes. People were very engaged with how the work reveals itself in stages, from the kaleidoscopic imagery displaying on the two way suspended screen to discovering the board of distorting lenses behind the screen and finally stepping back to see the original film from the human perspective before it is transformed by the lenses.

Referencing a many-eyed giant of Greek mythology, Argos Panoptes (always eyes still awake), the work considers the perpetual vigilance of rock as record keeper and witness. Video of human activity projected through distorting optical lenses transforms the anthropocentric position to imagine the perspective of the rock.

The pattern of lenses is informed by the molecular structure of magnetite, a mineral found in magma and metamorphic rock in Earth’s crust as well as in meteorites and the cells of organisms.

Through actual and metaphoric lenses, the relationship between the organic and non-organic is explored.

Mined magnetite is used in industrial and mechanical processes and its use in combustion engines and vehicle braking systems is releasing nanoscale pollutant particles into the air which are finding their way into human brain cells, vastly overwhelming the innate magnetite present, causing concerns linked to the development of degenerative brain diseases.

As well as referencing an ever watchful, many-eyed giant of Greek mythology, Lithos Panoptes also considers the numerous eyes (ocelli) of the chiton (a species of mollusc) whose rock crystal lenses have evolved over many millions of years to keep watch along rocky coastlines across the globe.

The only creature with eye lenses made of mineral and not protein, the chiton is also unique in having rows of teeth primed with magnetite which allow chomping on the hard rock surfaces it clings to. Some chiton’s teeth also contain the recently discovered mineral santabarbaraite, named after the mining district Santa Barbara in Italy where it was found – it is one of the few minerals named after a woman.

I was surprised to discover that the benedictions of Saint Barbara are still sought today, with shrines installed at tunnel entrances at Crossrail and even at CERN, the epicentre of scientific rigour. Before the boring machines were set in motion, services seeking her blessings were performed by local priests, with some even being winched down excavation shafts to carry out their duties.

Saint Barbara, who is associated with sudden death from fire, lightning and explosions, including military armaments, was adopted as patron saint of miners and tunnellers when the use of explosives in mining escalated during the 1600’s.

As the statues of Saint Barbara installed at these tunnel entrances are now buried, I have substituted images of my mother Barbara, coincidently born within hours of this Saint’s Day, in my video installation Lithos Panoptes.

Tucked into a dark recess of the gallery, Belly of a Rock suggests an imagined place of chemical conversations at the intersection of the organic and inorganic. A hybrid between rock, mollusc and technology this video sculpture responds to an early lifeform’s emerging self-awareness, desire to communicate and urge to create as described by Italo Calvino in his story ‘The Spiral’. We don’t always know what we are creating.

Thrilled to show these works alongside Julie F Hill @juliefhill, Rona Lee @ronaleeartist, Charlie Franklin @charlie__franklin and Deborah Tchoudjinoff @deboraht_ff

Julie F Hill’s sculptural print installation Parent Body uses scanning electron microscope imagery of samples recently returned from asteroid Bennu. The cave-like entrance, provides an embodied experience of the data and invites intimate contemplation of expanded scales. The ambiguous rock-like yet flowing forms echo the words of Jeffrey Jerome Cohen ‘stone is fluid when viewed within its proper duration’. Hill’s miniature work Return, considers the chemical and molecular cross exchanges between earth and space and in a gesture of reverse sample return (scientific missions and human extractive processes both take), a bead of Iridium is returned to the belly of asteroid Itokawa. Her small-scale embroidery work Water and Night, is based on observational studies of moonlight on water, continuing her explorations of water as the eye of landscape as proposed by Gaston Bachelard.

Deborah Tchoudjinoff’s moving image installation work The City of Gold (with sound in collaboration with Joe Farley) considers vast, beyond human, geological timescales when continents have once again become as one. Starting as a short fiction text, Deborah began to form an imagined world of cities in a future Amasia. The fictional cities are named after minerals that are heavily sought – rare earths, copper, uranium, gold, and coal – hinting at a narrative of an Earth depleted of the resources we rely on. The City of Gold is one of the five imagined cities. In a world where these natural resources are no longer, she questions what it would look like and who would be the inhabitants.

For Litho/Domous Rona Lee has chosen to work with book plates originating in the post-war period of the ‘great acceleration’ – a time in which population numbers, use of natural resources, popular consumerism, technological dependency and environmental degeneration burgeoned. Unified in their varying representations of the geologic but broking no contradiction between their celebration of extractive processes such as tourism and industrialisation and idealisation of the ‘wild’, the images selected by Lee conjure a pre-fall world in which imaginaries of lithic instability are firmly suppressed.

Two handfuls of silt (the residue of scientific samples collected at a depth of 4,000 meters), squeezed into the artist’s hands, fired and then gilded, form Rona Lee’s I want, I want, I want (2012), the title of which references William Blake’s engraving of the same name, wryly conjures the possibility of reaching down into the ocean’s depth, as though into a rock pool, while simultaneously cautioning against the folly and voracity of such ambitions.

The sculptures presented by Charlie Franklin, Landform and FRAGS, are lumpy, solid looking forms that speak of geological debris or ruins. All three pieces were soaked in the waters of the North Sea, on the easterly edge of the UK. This process allowed the natural elements to determine their individual patination or colouring, along with indentations and scuffs, where materials have been worn away by salt and stone. Cave Drawings (Aladdin’s Cave, Series of Grottos, Marble Curtain, Fairy Grotto, and Solomon’s Temple) are a series of five found postcards depicting the caves at Cheddar Gorge in Somerset, UK which have been hand coloured by the artist. Franklin is interested in how the addition of colour can provoke a personality or aura within each cave interior, allowing for grand experiments to be realised on an intimate scale.

A highlight of our events was an Urban Geology Walk led by geologist Ruth Siddall.

“The gravel pit, like other mining holes, is the reverse image of the cityscape it creates — extraction in the aid of erection.” Lucy Lippard

Ruth lead a group walk to explore the geology of the local built environment around Regent’s Place and Fitzrovia. Her knowledge of geology is astounding and her passion for stone infectious. Everyone came away incredulous, having their eyes opened to the deep time history of the rocks that build our city. The deep, black, Archaean dolerite from Mashonaland in Zimbabwe that Ruth points to is 2.2 billion years old. The large block of polished stone shaped like a giant pebble, itself crammed with pebbles of other rocks, is a sculpture by John Aiken, Monolith & Shadow. A patchwork of Jurassic limestone from southern Spain is crowded with the spire-shaped fossil shells of the gastropod Nerinea, stained red and yellow with ochres.

After the walk Ruth joined us for a tour of the gallery – it was fantastic to hear her insight and corroboration on some of the research that fed into the artworks.

I offered Lithomancy drop-in sessions on Friday afternoons as part of a programme of events for The Geological Unconscious. Visitors were invited to throw gemstones with specially assigned characteristics onto a wooden board divided into geologically themed sections. They are then given personal interpretations based on the position of the cast stones by drawing from the esoteric ritual of lithomancy which seeks to divine the future from the reading of stones.

This performative experience proposes insights into the power and allure of stones emanating from the symbolic meanings attributed to them and exposes the entangled relations between the human and the geologic found in our language and desire to align the human condition with the lithic.

We had many interesting visitors to The Geological Unconscious and have made some wonderful new contacts. Not least among these was meeting Melanie Wheeler who has recently completed a residency in the UCL Geology Department where she worked with the technician to re-curate the rock room. Julie and I were lucky to be taken on a tour of the newly curated collection and receive gifts. So excited to have a beautiful sample of magnetite.

In ancient Greek, magnetite was known as “magnes lithos,” meaning “stone from Magnesia” – the region in Thessaly, Greece, where magnetite was first discovered, supposedly by a shepherd who noticed the nails in his boots were sticking to the rock under his feet.

As an additional daily drop in activity during The Geological Unconscious we offered cheong tasting. Chef Moonhyung Lee explored human-mineral entanglements through digestion using stones to create cheong (Korean fermented syrup). The use of weighing stones helps create the environment for preservation, a process which amplifies the bioavailability of minerals in food. Moonhyung Lee is a food designer with a background in graphics. She is currently based in London and works at zero waste restaurant Silo.

It was great to have so many people join us for our Closing Event artist talks and the launch of the exhibition publication with preface by Jason Groves and short essay by Ruth Siddall.

We also had the microscope set up at the closing event to look at some crystal growth in solutions prepared by Julie who works extensively with crystals.

I had tried some ‘Vitamin C’ crystal growing microscopy experiments at home. These images use a polarising filter under the microscope to reveal the vibrant colours. Next step will be to set up a timelapse of the crystals growing.

Summer Solstice 2025. The shortest night of the longest day brought an awful darkness. Collected the last two solargraphs I had installed at the Hogsmill Nature Reserve. These have been collecting light from the sun for a whole year, recording every sunrise and sunset. May the light shine through.

I was delighted that my video Cosmic Chiasmus: crossing the universe was included in CARBON: Under Pressure, at the Mazumdar-Shaw Advanced Research Centre as part of Glasgow Science Festival 2025, in a special exhibition partnership with Science Gallery Bengaluru.

The video offers a glimpse into a subatomic world where cosmic rays travel from distant galaxies to collide and silently interact with atoms and technology on Earth. Alongside the screening of the video I was also invited to give an artist talk and cloud chamber demonstration. It was great to share the wonders of the cloud chamber with visitors who were able to see cosmic ray trails for themselves.

It is an incredible journey that cosmic rays make, blasted across space, spiralling along magnetic field lines to end up entangled with carbon in our bodies.

Not only is all life physically permeated by cosmic rays with the potential for nuclei collisions, but some cascading particles smash into atoms of nitrogen and combine with oxygen to create radioactive carbon-14 which enters our atmosphere. Plants absorb it during photosynthesis, and it is incorporated into their carbon skeleton, which we then eat. While plants and animals are alive, carbon-14 is continually replenished as the organism takes in air or food. But when an organism dies no more carbon-14 is absorbed and that which is present starts to decay at a constant rate. By measuring the radioactivity of dead organic matter, the current carbon-14 content can be determined and the time of death established. Cosmic ray activity gives us carbon dating techniques.

Reading

The Geological Unconscious – Jason Groves. Returning to this book that sparked the ideas we explored in our exhibition. A redirection of geology to consider a type of connection between things that are not in themselves geologic. Stones that stare, stones that speak. An image of the human could develop through geologic processes, becoming part of the mineral consciousness. Quoting Heather Sullivan ‘There is a difficulty for biology and philosophy to maintain a reliable distinction between life and non-life.’

The Writing of Stones – Roger Caillois. A paean to the capacity of minerals to form images within the imagination, which in turn is considered to be nothing more than an extension of matter.

The Performances of Sacred Places: crossing, breathing, resisting – edited by Silvia Battista. I read this for some background research while thinking about how I might make work responding to the abandoned sites of the cosmic ray detector huts at Haverah Park on the North Yorkshire Moors.

‘An horizon stands, in modern hermeneutics, for what is possible to see from the position of a specific observer. That is, not only a location in space but also a position in the cultural and historical apprehension of the world.’ Silvia Battista

The book opens by questioning relationships between the site and its ascribed attributes, which may be mercurial qualities not easy to define or quantify. It reflects on the performativity theories of Karen Barad which argue that matter, in its complexity, is an active participant in our relationship to the world and Jane Bennet’s call to recognise the ‘vitality of matter’ that crosses the human non human divide. In the section on ‘crossing’ the sensitive work of Louise Ann Wilson explores ritual around death, grief and loss through walking in rural locations echoing walking an interior landscape of memory. Walking the labyrinth and the pilgrimage are also considered as journeys that take place in physical and metaphysical space.

‘What truth could be more unexpected ….than the one in which the mineral envisions while also being envisioned.’ Jason Groves, The Geological Unconscious

‘This is the blueprint of nature itself; both hidden and revealed in a nodule of silica.’
Roger Caillois, The Writing of Stones

The Geological Unconscious opened with an exceptionally busy Private View. It was a fantastic evening with lots of great feedback. With a multi-disciplinary approach, large-scale installations and sculptural works sit alongside embroidery, video, expanded print and photographic work, to create material intimacies that help situate us in scales beyond the human.

My video installation Lithos Panoptes imagines a view of the world from the perspective of the rock via the molecular structure of magnetite. Referencing a many-eyed giant of Greek mythology, Argos Panoptes (always eyes still awake), the work considers the perpetual vigilance of rock as record keeper and witness.

Video of human activity projected through distorting optical lenses transforms the anthropocentric position to imagine the perspective of the rock.

Magnetite is a mineral found in magma and metamorphic rock in Earth’s crust as well as in meteorites. Magnetite nanoparticles are also found naturally in organisms and are known to aid magnetoreception, a
means whereby animals and birds orientate themselves by sensing polar direction.
Through these actual and metaphoric lenses the relationship between the organic and non-organic is explored. Imagery includes allusions to scientific research into the dramatic overwhelming of innate magnetite in human brain cells by nanoscale pollutant particles of magnetite released into the air by traffic; the unique qualities of the chiton, a mollusc with hundreds of tiny eyes made from rock rather than biological material and teeth primed with magnetite and containing recently discovered mineral santabarbaraite; Saint Barbara, patron saint of miners and tunnellers, adopted when the use of explosives in mining escalated in the 1600’s and whose benedictions are still sought today with shrines installed at tunnel entrances at Crossrail and even at CERN, the epicentre of scientific rigour.

Also showing the video sculpture Belly of a Rock – describing an imagined place of chemical conversations at the intersection of the animate and inanimate. Under a crusted shell, surfaces slide and scrape along lines of fissure, distended innards ooze and rocks moan as they are distorted by untold pressure. The turbulent spiralling of the molten core births rock and lifeforms which are acted upon by the drag of an oscillating magnetic field.

Julie F Hill’s large-scale sculptural print installation Parent Body, uses scanning electron microscope imagery of samples recently returned from asteroid Bennu. The data features detail of carbon-rich and organic ‘nano-globules’ which have been theorised as ‘proto-cells’. The sculpture evokes astro-geological-biological material lineages across deep space and cosmological time. In a contrast of scale, Julie is also showing Return, 3d print of asteroid Itokawa cast in plaster-of-paris with a bead of Iridium. Iridium is an rare-earth element more abundant in asteroids than the Earth’s crust. This miniature work considers the cross exchanges between space and earth and in a gesture of reverse sample return (scientific missions and human extractive processes both take), a bead of Iridium is returned to the belly of asteroid Itokawa.

Charlie Franklin’s work considers control, physical experience and memory within the natural landscape. Her research includes how formations such as standing stones, grottos and geological debris remain or change across time. With a particular interest in materials and the properties they hold, she is experimental in her approach to making. Everyday items including cardboard, plastic sheeting and gaffer tape are repurposed to build the foundations of her sculptural work. Franklin also collects found imagery such as postcards and photographs, which she reworks to become something else.


In Litho/Domous, Rona Lee layers photographic plates from mass produced ‘coffee table’ books onto lighting panels, utilising the ‘bleed’ between them that this reveals, to evoke the tectonic instabilities of
contemporary eco relations. Originating in the post war ‘golden age of capitalism’, and designed as statement pieces for home display, the aspirational focus of these image-rich publications on culture, travel, landscape, can be said to prefigure the arc of the smartphone in making the world consumable. At the same time titles such as The Mineral Kingdom and Library of Nations speak to the legacies of the Enlightenment project, offering up an order of things in which Mankind / the Anglophone world is positioned as ascendant and Nature – along with ‘other’ cultures – is ‘put on the table’.

Deborah Tchoudjinoff’s video installation The City of Gold takes a speculative look at Earth in the far future. Her work considers vast, beyond human, geological timescales where continents have once again become one. Past supercontinents create room to speculate upon future ones if we understand Earth as shifting, moving matter. Starting as a short fiction text Tchoudjinoff began to form an imagined world of cities in a future supercontinent of Amasia. The fictional cities named after the minerals that are heavily sought – rare earths, copper, uranium, gold, and coal – hinting at the narrative of an Earth depleted of the resources we rely on. The City of Gold is one of five imagined cities.

An accompanying events programme includes an urban geology walk with Geologist Ruth Siddall, discussing the origins of the local built environment; Cheong tasting by chef Moonhyung Lee who explores human-mineral entanglements through digestion; a crystal growing workshop led by Julie F Hill and I will be offering visitors lithomancy readings every Friday afternoon. The reading of stones proposes insights into the power and allure of stones emanating from the symbolic meanings attributed to them and exposes the entangled relations between the human and the geologic found in our language and desire to align the human condition with the lithic.

Once I start thinking of minerals as something we swallow to make our body function, I also start to think of how our body comes to be composed of these minerals, and that when we gradually decay after death we become mineral components again. So, the gesture of swallowing a tablet or vitamin pill is as magical, or let’s say as supernatural, as we want, because we really are swallowing a stone. – Otobong Nkanga

Link to Marina Walker essay The Writing of Stones published by Cabinet Magazine.

London once had many stones. They made convenient landmarks for gatherings and councils, or else marked boundaries or distances. As a result, they often crop up in place names – Link to The Londonist ‘Lost Stones of London’.

Gallery visits

Mónica Alcázar-Duarte in Cultural Reforesting Exhibition at Orleans House Gallery. In this exhibition, the artists remind us that we not only have a relationship with nature but also that we are nature. We are human animals. Together, with our more-than-human neighbours, we are a growing, singing, howling forest. 

Under the big Suffolk skies of Orford Ness. Walking landscape that bears the scars, physical and emotionally resonant, of years of intense military top secret experiments. Here radar was developed, the aiming of bombs was refined, material vulnerability was tested with destructive, explosive projectiles under simulations of attack and famously it is the site of environmental tests during the late 50’s, early 60’s, in the development for detonation of the atomic bomb. 

The weight of the shingle shored up around the buildings and on the roofs used to dampen the explosions.

There is a lot to respond to. It is now a spectacular nature reserve but apparently not so many birds here this year. We were lucky to see a short eared owl hunting and some gangly spoonbills in flight.

Kaori Homma Silent Echoes at The Watch House, Orford Quay – Inspired by Orford Ness, the UK’s only site of atomic experimentation, this exhibition explores the hidden histories and lingering memories within its landscape. Through the unconventional method of Aburi dashi or fire etching, the artist explores not only the visible remnants of the secret history of Orford Ness, but also the unspoken memories that linger in the air. Unlike ordinary drawings made by the pigments on the surface of paper, Homma’s works are made by fire which etches the images into the body of paper as a burn mark.

Electric Dreams at Tate Modern celebrates the early innovators of optical, kinetic, programmed and digital art, who pioneered a new era of immersive sensory installations and automatically-generated works. This major exhibition brings together ground breaking works by a wide range of international artists who engaged with science, technology and material innovation. 

Desmond Paul Henry used a repurposed bombsight computer, designed to drop bombs more accurately, as developed at Orford Ness, to make a drawing machine which he then hand embellished.

The Pleasure of Misuse curated by Indira Dyussebayeva-Ziyabek and Maria Hinel at Royal Society of Sculptors. ‘The humour that springs from manipulating or referencing the mundane is paradoxically self-reflexive – appropriated objects suddenly appear anthropomorphic, our laughter becomes directed at ourselves and the intermittent absurdity of the human condition. The Pleasure of Misuse explores the mechanics and psychology of humour in the everyday, considering its potential to heal and its power to disarm, creating the sense of complicity and the space for self-reflection amid these anxious times.’

Samuel Zealey, Angela Eames, Tony Fleming, Charlotte Guerard, John Strutton and Kate Fahey in Heavenly Skeletons at Coleman Project Spacesix contemporary artists whose work repositions drawing as an expanded multidisciplinary field.  Heavenly Skeletons is a dynamic investigation of how drawing translates abstract concepts into tangible form… 

Gorgeous show with thoughtfully chosen works that like Samuel Zealey’s vertiginous sculpture balance perfectly.

It has been a busy few weeks preparing for The Geological Unconscious at Hypha HQ – a group exhibition, co-curated by Julie F Hill and myself, exploring themes of stone consciousness and human-mineral encounters, destabilising assumptions about passive matter and a stable Earth.

Congo, 14 × 20.5 × 6 cm. Photographed in the Museum of Natural History, Paris by Julie F Hill.


Responding to Jason Groves’ inquiry into the mineral imaginary in his eponymous book, as well as the ‘Writing of Stones’ as proposed by writer and mineral collector Roger Caillois, the exhibition exposes the complex entanglements between the organic and the inorganic; the human and the lithic. The Geological Unconscious is viewed through disruptive Surrealist strategies, engagements with the aesthetics of geo-materiality and material processes that attend to the growth and transformation of matter. These artistic ‘excavations’ highlight the toll of extractive industries on our planet, whilst inspiring reverence for the geological lineages of deep, cosmic time. Theories of Animism and Panpsychism are also brought to
bear on ways of attributing agency to inorganic realms.

I am thrilled to be exhibiting with Julie F Hill, Charlie Franklin, Rona Lee and Deborah Tchoudjinoff.


An accompanying events programme includes an urban geology walk with Geologist Ruth Siddall, discussing the origins of the local built environment; an installation and tasting by chef Moonhyung Lee who explores human-mineral entanglements through digestion; a crystal growing workshop led by Julie F Hill and I will be offering visitors lithomancy readings every Friday afternoon.

Investigating human/mineral entanglements for new work to be installed at Hypha HQ for The Geological Unconscious. Video of human activity projected through distorting optical lenses transforms the anthropocentric position to imagine the perspective of the rock. The pattern of lenses is informed by the molecular structure of magnetite,

Magnetite is a naturally magnetic mineral found in many organism’s cells including human brain cells. Mined magnetite is used in industrial and mechanical processes and its use in combustion engines and braking systems is releasing nanoscale pollutant particles from traffic into the air which are finding their way into brain cells in high percentages causing concerns with links to degenerative brain diseases. I have been filming the stop start constant stream of traffic at a local roundabout and made a cast of a brain in gelatine with suspended iron filings. The filings oxidised and so the brain took on an iron red tinge and after a few days it cleaved down the centre and gradually as it dried became more and more chiton like.

Chitons are remarkable molluscs that have changed little in hundreds of millions of years. The chiton has hundreds of tiny eyes in its shell, which is made of eight articulating plates. It is the only known creature with lenses made of minerals rather than protein. Another distinctive feature of the chiton is having rows of teeth primed with magnetite, which aid its homing capabilities through magnetoreception and allow chomping on the hard rock surfaces it clings to. Inside the teeth of some species, the mineral santabarbaraite has been found, named after Santa Barbara, a mining district in Italy where it was first discovered and that honours Saint Barbara, who is the patron saint of mining and tunnelling. Santabarbaraite is also one of the few minerals named after a woman.

Fantastic day chiton hunting in the rockpools on the stunning East Sussex coast. Thanks to family who helped find these well camouflaged unique creatures.

Saint Barbara, was adopted by miners and underground workers as patron saint after the pursuit of geology and the widespread use of gunpowder in mining escalated in the 1600’s. She may have a dubious authenticity but her benedictions are still sought today with many statues installed at the entrances to Crossrail and a large ceremony on her saints day, 4th December, performed by local priests before tunnelling went ahead. Even at CERN the epicentre of scientific rigour, a shrine to Saint Barbara was established at every shaft site of the Large Hadron Collider requiring excavation and a blessing performed even if the priest had to be lowered by crane down the shaft to achieve this.

My mother’s name was Barbara and her birthday 6th December is very close to Saint Barbara’s day on the 4th. It would be great to discover she arrived two days late but there is no one alive now to ask.

Small grains of magnetite are common in igneous rocks, formed from magma having cooled and solidified within the Earth’s crust, and also in metamorphic rock, formed when existing rock is transformed physically or chemically at extreme temperatures. 

These processes happen on other planets as well as Earth and so magnetite has also been found in meteorites.

Using a digital microscope to look at the structure of the chondrite meteorite NWA 16975 discovered in the Sahara in 2024 which displays numerous and obvious chondrules and flecks of nickel iron in a fine grained matrix.

Also the fragment I have from the Diogenite meteorite NWA 7831 found in Morocco in 2013.

Looking at wonderfully colourful geological maps of Greece to locate the ancient area of Magnesia – the region where magnetite was first discovered and where its name has derived from – known as “magnes lithos” (stone from Magnesia). Definitely want to plan a research trip to this beautiful region around Thessaloniki.

Exhibitions

Whatshesaid collective of artists present Terra Incognita at Thames-side Studios Gallery – charting and cataloguing the disregarded, the everyday, its surface textures, accumulations, sedimentations.

Joao Villas and Victoria Ahrens showing in Spectral Matters at APT Gallery An understated beautifully curated show whose work references the ephemeral materiality of sound, video, photography and print. The work overlaps and crosses over, both artists responding to the other’s practice. The images create matter, as spectral matter gives agency to the materiality of its own making, while haunting the space with its frequency- it vibrates. The exhibition explores memory, technology and the Anthropocene- and how the disappearing materiality of the world is captured through ephemeral means.
