From Wikipedia: "Tod Dockstader (March 20, 1932 – February 27, 2015) was an American composer of electronic music, and particularly musique concrète. He studied painting and film while at the University of Minnesota, before moving to Hollywood in 1955, to become an apprentice film editor. He moved into work as a sound engineer in 1958, and apprenticed at Gotham Recording Studios, where he first started composing. Dockstader's first record, Eight Electronic Pieces, was released in 1960, and was later used as the soundtrack to Federico Fellini's Satyricon (1969). He continued to create music throughout the first half of that decade, working principally with tape manipulation effects. In 1966 Owl Records released four albums of his work from this period including what many consider to be Dockstader's masterpiece, Quatermass."
