Sediment is an assemblage of field recordings made in the Swiss canton of Jura on a single day in August 2022. Jura's rock and limestone formations create a complex topology which hosts a diversity of sound spaces; human, more-than-human, geophonic, subterranean and extra-terrestrial. By walking and driving through this landscape curious pockets of activity are revealed to the listener. The layers of strata that make up Jura; earth, rock, forest, cables, pipes, factories, planes and radio towers inform the sound strata. These recordings incorporate and embrace these many layerings; the acoustic, radio, magnetic, vibrational, tectonic, resonant.

Over the course of a day Tim Shaw and Laurent Güdel followed their ears, they visited forests, mountains, rivers, hydroelectric plants, caves, radio broadcast towers, wind turbines, train tracks, sacred wells, man made tunnels and abandoned factories, harvesting sounds from this tangled and ever-changing soundscape. Using various listening devices they attempted to listen into the full spectrum of activity, hydrophonic, geophonic, air-pressure, electromagnetic and radio.

Sounds harvested include pieces of limestone being submerged into water, electromagnetic fall out from cell towers, the resonance of a limestone processing factory, VLF radio, the mechanisms of infrastructure, radio controlled airplanes and acoustic signals. These files are mixed and blended together to create a new stratification.

The final compositions were separately pieced together in each of the artist's studios using the collective corpus of recordings. The result is two different sonic interpretations of this layered, ancient and complex landscape.

Tim Shaw works with sound, light, and communication media to create performances, installations, and site-responsive interventions. His practice spans environmental sound art, digital media, media archaeology and walking. He frequently presents his work at festivals, in forests, caves, warehouses, up mountains, and in museums and art galleries all over the world.

Laurent Güdel explores analogue synthesis, phonography, and sound archives through multi-channel electroacoustic compositions, live performances, installations, and audio publications. His work explores the politics of sound, the means of production of early electronic music, and the archaeology of audio technologies, their infrastructures and institutions. He is also co-curator of Kopfhörer, a series dedicated to live experimental music.
