Klaus Schulze (born 4 August 1947) is a German electronic music composer and musician. He also used the alias Richard Wahnfried. He was briefly a member of the electronic bands Tangerine Dream and Ash Ra Tempel before launching a solo career consisting of more than 60 albums lasting five decades. In 1969, Klaus Schulze was the drummer of one of the early incarnations of Tangerine Dream for their debut album Electronic Meditation. In 1970 he left this group to form Ash Ra Tempel with Manuel Göttsching. In 1971, he chose again to leave a newly-formed group after only one album, this time to mount a solo career. In 1972, Schulze released his debut album Irrlicht with organ and a recording of an orchestra filtered almost beyond recognition. Despite the lack of synthesizers, this proto-ambient work is regarded as a milestone in electronic music. The follow up, Cyborg, was similar but added the EMS Synthi A synthesizer. Since this point, Schulze's career has been most prolific, and he can now claim more than 40 original albums to his name since Irrlicht. Highlights of these include 1975's Timewind, 1976's Moondawn (his first album to feature the Moog modular synthesizer), 1979's Dune.
