Berlin record label m=minimal credits Stiebler (Berlin, 1934) with being the first German composer to explore minimal techniques in his works in reaction to the serialism dominant at the time. Though his compositions are relatively unknown, Stiebler has garnered enormous respect for his long radio production career.
Stiebler is a highly respected avant-garde composer; he writes for piano and organ, and has created chamber music and choir pieces. He served as director of new music at Hessischer Rundfunk for over 25 years where he supervised recordings of Morton Feldman, John Cage, Alvin Lucier, Giacinto Scelsi, Earle Brown, and Christian Wolff, among others
Stiebler studied composition and piano at the Musikhochschule Hamburg and in Darmstadt between 1958 and 1961, including a period studying with Karlheinz Stockhausen in 1959.
His first composition “Extension I” was performed in 1963 and was seen as being in opposition to the serialist styles that were dominant at that time. His “Sequenz II” for cello and tape (1984) has been released by m=minimal in 2012 as a new recording with cellist Agnieszka Dziubak. The release also comprises the pieces “Mitteltöne”, and “Trio 89”. In the near future, m=minimal will release Stiebler’s ton um ton performed by ensemble modern.
