Asmus Tietchens

Active since the mid-1960s, the Hamburg-based synthesizer experimentalist and musique concrète producer Asmus Tietchens has exerted a formative influence on successive waves of avant-garde electronic musicians and sound artists. Drawing deeply from Karlheinz Stockhausen, Tietchens has chased “absolute music” by means of strict formal procedures, yielding work that is frequently severe, otherworldly, and abstract, even as he has also produced several collections of oddly playful material—among them his early-1980s Sky Records releases and subsequent projects issued under the Hematic Sunsets moniker. Beyond more than one hundred recordings, many of them realized in tandem with Merzbow, Vidna Obmana, and Thomas Köner, Tietchens has instructed acoustics at Hamburg universities since 1990 and has supplied liner notes for numerous Bureau B releases, most notably reissues of Cluster-related material.

Born in 1947, Tietchens absorbed pioneering electronic broadcasts by Stockhausen and Gottfried Michael Koenig on German radio during childhood. He commenced private recording experiments in 1965 using rudimentary reverb units and later acquired a MiniMoog; atonal Krautrock acts such as Cluster and Faust supplied additional impetus. An encounter with Okko Bekker inaugurated a decades-long collaboration in which Bekker produced the bulk of Tietchens’s output. Tietchens also joined the supergroup Liliental, whose members included Cluster’s Dieter Moebius, engineer Conny Plank, bassist Hellmut Hattler, saxophonist Johannes Pappert, and Bekker; the ensemble’s self-titled album appeared on Brain in 1978.

After Tangerine Dream’s Peter Baumann encountered a demo tape, he produced Tietchens’s debut, Nachtstücke, issued in 1980 by the French label Egg. The four early-1980s Sky albums—Biotop, Spät-Europa, In die Nacht, and Litia—emphasized unexpectedly approachable electronic pop, yet 1984’s Formen Letzter Hausmusik, recorded for Nurse with Wound’s United Dairies imprint, inaugurated a sustained phase of abstract, concrète pieces that incorporate both tape manipulation and synthesizers, documented on A-Mission Records, Discos Esplendor Geométrico, and Multimood. Invited by the Goethe-Institute in 1986, Tietchens began presenting lecture-concerts across South America, after which his Hamburg teaching commitments commenced.

Throughout the 1990s he contributed to numerous experimental imprints including Barooni, Staalplaat, and Syrenia. In 2000 he launched the Menge series of rigorously minimal microsound works, first on Mille Plateaux’s Ritornell sublabel and subsequently on Richard Chartier’s Line imprint. Beginning in 2003, Die Stadt undertook the first CD reissues of Tietchens’s early catalog, commencing with the Sky titles; Tietchens authored liner notes for these editions as well as for Cluster-related reissues. A 2012 collaboration with Moebius yielded a self-titled album on Bureau B, which later reissued the Sky catalog on both CD and vinyl, appending the bonus material from the Die Stadt editions as Der Fünfte Himmel. Further releases have continued to appear on Auf Abwegen and Stille Andacht.
