In 1966, Raben, together with several others, founded the Action Theatre in Munich, which led to the Anti Theatre in 1968, where he was active as writer, composer and director. In 1969 and 1970 he produced Fassbinder’s first films. After working on a film of his own (Die Ahnfrau), he concentrated on composing for theatre and films.
In addition to Fassbinder, Raben composed music for Robert van Ackeren, Barbet Schroeder, Daniel Schmid, Bernhard Sinkel, Peter Zadek, Doris Dörrie, Hansgünther Heyme, Ulrike Ottinger, Werner Schroeter, Tom Toelle, Dan Polsby, Percy Adlon, Wong Kar-wai and Sergej Stanojkovski.
