Conrad Schnitzler (1937-2011), composer and concept artist, is one of the most important representatives of Germanys electronic music avant-garde. A student of Joseph Beuys, he founded Berlins legendary Zodiak Free Arts Lab, a subculture club, in 1967/68, was a member of Tangerine Dream (together with Klaus Schulze and Edgar Froese) and Kluster (with Dieter Moebius and Hans-Joachim Roedelius) and also released countless solo albums. On "Congratulacion" he experimented with the Yamaha CX5 synthesizer, new on the market. The results were surprisingly structured and harmonious for Schnitzler. "Congratulacion" was first released in 1987 on the small Spanish label Esplendor Geometrico. Featuring six Bonustracks. Essay by Asmus Tietchens.
