Frank Bretschneider is a German electronic musician. He works primarily with sine waves and white noise as his source material. He also releases material under the name Komet.

Bretschneider was born and raised in Karl-Marx-Stadt (now Chemnitz) in the German Democratic Republic (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 (German: work group violin), which was influenced by the Dada art movement, The Residents, and Soviet science fiction. AG. Geige disbanded in 1992.
