Asmus Tietchens

All Music Guide:

Synthesizer experimentalist and musique concrète producer Asmus Tietchens began recording in the mid-'60s and continued to record three decades after that. Born in 1947 and based in Hamburg, Tietchens listened to German radio as a child and heard pioneering electric transmissions by the likes of Stockhausen and Gottfried Michael Koenig. He began recording his own home experiments in 1965 with crude reverb devices and picked up a MiniMoog several years later. Also influenced by atonal Kraut-rockers like Cluster and Faust, Tietchens met Okko Bekker and began a partnership that lasted for decades (Bekker has produced most of Tietchens' work). After Tangerine Dream's Peter Baumann heard a tape of his work, he produced Tietchens' debut album Nachtstücke, released in 1980 on Sky Records. His four albums for Sky during the early '80s focused on surprisingly accessible electronic pop, though 1984's Formen Letzter Hausmusik (recorded for Nurse with Wound's United Dairies label) began a period of more abstract, concrète recordings that often use tape experiments as well as synthesizers. During the '90s, Tietchens recorded for experimental labels Barooni, Staalplaat and Syrenia, the latter a 1996 collaboration with Vidna Obmana. Since 1990, he has also taught sound at a Hamburg university.

Asmus Tietchens (born 3 February 1947, Hamburg), who also records under the monikers Hematic Sunsets and Club of Rome, is a German composer of avant-garde music.

Tietchens became interested in experimental music and musique concrète as a child, and began recording sound experiments in 1965 with electronic musical instruments, synthesizers and tape loops. In the 1970s he met producer Okko Bekker, and the two formed a decades-long partnership. Peter Baumann (of Tangerine Dream) heard a recording of Tietchens' music and offered to produce an album; the result was Nachtstücke, Tietchens' 1980 offering on Sky Records. His early recordings feature more accessible synthesized music, but beginning with Formen Letzer Hausmusik, his 1984 release for Nurse With Wound's label United Dairies, he began moving toward more abstract sound collages. He has taught acoustics in Hamburg since 1990.
