Frank Bretschneider was active in the subcultural environment of Karl-Marx-Stadt. In the early 1980s, he published the independent graphics edition “A Drei”, then went on to set the tone with cult formation AG Geige.rnrnUnder the alias A.F. Moebius, Bretschneider’s “Eine Auswahl” (“A selection”) was a distillate of creative periods from 1985 to '87. The B-side “Eine Auswahl” complemented the “Alle Aufnahmen” (“All recordings”) tape by Heinz & Franz, a project that would close the circuit of acoustics and electronics. “Eine Auswahl” was based on work with the KORG M-20; Bretschneider also worked with tape loops. Material used included fragments, musical phrases, AMIGA radio play records or randomly targeted radio snippets.rnrnThe split tape by Heinz & Franz and A.F. Moebius was released in 1988 on Bretschneider’s underground label klangFarBe in an edition of about 50 copies. Between 1985 and '89, eight tape productions appeared on klangFarBe.
