In 1972 Ash Ra Tempel asked him to join them as singer for their recording of the psychedelic album Seven Up, that took place in collaboration with Timothy Leary in the Sinus Studio in Bern, Switzerland.

After recording the album Metropolis and releasing the single "Super Plastic Club", the band produced a multi-media show based on Ray Bradbury's The Illustrated Man, before they split in 1976.

In 1977 he founded Albatros Concerts and for a short time promoted bands like Patti Smith, Bob Marley, Blondie or early Dire Straits before he again concentrated on his career as composer and musician.

Together they produced his first solo work, Mickie D’s Unicorn, an album full of dragons, witches, fairies and elves, which set a milestone in the fusion of pop and synthesizer music at the time, and with guest musicians ranging from Manuel Göttsching (Ash Ra Tempel) to Michael Shrieve (Santana).

Since the mid 1990s he writes and produces soundtracks for German TV-documentaries, docu-dramas such as Sphinx - Geheimnisse der Geschichte (also known as ZDF Expedition), Terra-X and movies such as Polizeiruf 110, often in collaboration with his long-time partner Torsten Sense.
