David Toop (born 1949) has been developing a practice that crosses boundaries of sound, listening, music and materials since 1970. This encompasses improvised music performance, writing, electronic sound, field recording, exhibition curating, sound art installations and opera. It includes seven acclaimed books, including Rap Attack (1984), Ocean of Sound (1995), Sinister Resonance (2010), Into the Maelstrom (2016) and forthcoming - Flutter Echo, a memoir first published in Japan in 2017 (May 2019) and Inflamed Invisible: Writing On Art and Sound 1976-2018 (2020). Briefly a member of David Cunningham’s pop project The Flying Lizards in 1979, he has released thirteen solo albums, from New and Rediscovered Musical Instruments on Brian Eno’s Obscure label (1975) and Sound Body on David Sylvian’s Samadhisound label (2006) to Entities Inertias Faint Beings (2016). His 1978 Amazonas recordings of Yanomami shamanism and ritual were released on Sub Rosa as Lost Shadows (2016). In recent years his collaborations include Rie Nakajima, Akio Suzuki, Tania Chen, John Butcher, Ken Ikeda, Elaine Mitchener, Henry Grimes, Sharon Gal, Camille Norment, Sidsel Endresen, Alasdair Roberts, Thurston Moore, Ryuichi Sakamoto and a revived Alterations, the iconoclastic improvising quartet with Steve Beresford, Peter Cusack and Terry Day first formed in 1977.
