A purveyor of digital manipulations of existing music, Ekkehard Ehlers released his debut, Betrieb, in 2000. The record significantly manipulates examples from such early 20th hundred years composers as Arnold Schoenberg and Charles Ives, Ehlers viewing each piece like a shut program with which to test. He spent some time working on the trilogy of mini-albums which he assumes the nature of great performers from days gone by and applies it to consumer electronics. The first with this series was Ekkehard Ehlers Takes on Robert Johnson accompanied by Ekkehard Ehlers Takes on Albert Ayler, which he manipulated compositions for cello. The ultimate record in the trilogy was Ekkehard Ehlers Takes on John Cassavetes. With Stephan Mathieu, he documented Heroin. Furthermore, he has documented beneath the alias Auch, aswell much like the duo Autopoesies as well as the group März.
