Tremenheere Gallery is pleased to present Sediment of Sleep, a group exhibition featuring works by Harriet Bowman, Rachael Champion, Rosanna Martin, ATOI, and Jack Whitefield, curated by ATOI. The exhibition explores the process of material collapse while offering glimpses of resilience and transformation, building on situations that evoke the interconnectedness and transience of the natural, imagined, industrial or post-Anthropocene world; where past, present, and future melt into each other like liquid time across architectural, geological, ecological and human forms.
Sediment of Sleep becomes an exploration of the layered interplay between form and decay, presence and absence, body and material awareness and unconsciousness—aligning with the artists’ interdisciplinary explorations of transformation and critical material engagement. The works are both industrial and vulnerable, transformative and ruinous-rooted in the physical world yet extending into imagined, speculative realms.
The title refers to quiet, often imperceptible layers of influence that accumulate over time in both the human psyche and the environment. Just as sediment records history through layering, the concept reflects the residue of lived experience, industrial intervention, and non-human temporalities. The phrase evokes a dream-like stillness or dormancy, where transformation brews beneath the surface. In this context, the title reflects the artists’ deep connection to materials and their hidden backgrounds; such as memory, by-products, erosion, and renewal, that carry the histories of landscape, self, industry, and ecology.
Featuring six artists, through sculpture, installation, photography and material intervention the exhibition explores the lasting subtle impacts of industrial systems, the blurring of boundaries between humans and the natural world, and the ongoing breakdown and rebuilding of both physical and ideological structures. Here, material is extracted, reclaimed, examined and transformed. These practices reflect a sensitivity to the rhythms of decay and regeneration and to the quiet resistance of more than human worlds.
