Frank Bretschneider (born 1956) is a German electronic musician. He works primarily with sine waves and white noise as his source material. Bretschneider was born and raised in Karl-Marx-Stadt (now Chemnitz) in the former German Democratic Republic (aka East Germany). In 1984, inspired by science fiction radio plays and films, he began experimenting with tape machines, synthesizers, and modified guitars. In 1986 he formed the band AG.GEIGE, which was influenced by the Dada art movement, The Residents, and Soviet science fiction. AG.GEIGE disbanded in 1992.
