C.E.S. vs. Felicity Mangan (Plants and Animals) brings together both artists personal investigation into the sound phenomena produced by plants and animals - through the combination of c.e.s. submerged sonification of plant biochemistry, deploying self-built synthesizers, to capture and sonify of the chemical composition of plants. Mangan explores the timbre and forms of found and self-recorded animal voices while mimicking biophonic patterns to create minimal quasi-bioacoustic environments, utilizing a sampler and sequencer. Together they create electro-acoustic compositions grafting field recordings, live and pre-recorded drones and pulses produced by remnants of plant biochemistry subterranean together with modified animal voices embedded in a bioacoustic sphere of synthetic and oscillating hybrids.
