Since the mid-'60s, synthesizer and musique concrete experimentalist Asmus Tietchens has been an enduring symbol of artistically motivated musical work. This album, the 12th in an ongoing series of his works and the second in a four part series originally released on Hampster Records, sees Tietchens "recycling" previous pieces made between 1967 and 1970. Originally released in 1989, the album is intended more as a demonstration of the variety of techniques utilized than a presentation of new pieces culled from old works.
