Asmus Tietchens is a sound artist and composer from Hamburg, Germany. He got interested in Musique Concrete by listening to a German radio program when he was ten years old. In 1965, at the age of 18, Asmus started experimenting with tape loops and turned them into musical collages. Soon, the use of synthesizers was added. In 1980 his debut album Nachtstücke was released, produced by Peter Baumann of Tangerine Dream. This was soon followed by a series of albums of electronic pop music for the Sky label, home of many Krautrock bands. Tietchens often uses special source materials for his compositions such as water ('Seuchengebiete'), human voices ('Von Mund zu Mund'), paper ('Papier ist geduldig'). He is associated with the industrial music scene through his collaborations and releases on labels such as United Dairies, Esplendor Geometrico or Dom Records.
Tietchens never studied composition, he has no academic background, everything he does is self-taught or learning by doing. Nevertheless, he was professor for sound design in Hamburg in recent years. Ptomaine was originally released on RRRecords in 1996 as a 3 LP set. This is the second volume of the first ever CD re-issue.
