Four political tape compositions 1976-1979 by Swiss composer Max E.Keller (b.1947). A rare case of left-wing / socialist electroacoustic music. The CD includes Keller's piece from the long out-of-print and sort of legendary Split-LP with Martin Schwarzenlander from 1977 plus 3 previously unreleased tape compositions. Max E. Keller originally started out as one of the first Swiss Free-Jazz musicians in the mid 1960's and studied composition with Hans Ulrich Lehmann and Helmut Lachenmann, and electronic music with Nicolaus A. Huber und Dirk Reith. In 1972 he was expelled from the Darmstadt International Summer Courses for New Music because of his political stances. Since the early 1970's Keller wrote more than 150 pieces for various forces which are performed internationally. Since 2007 he is chairman of the Swiss Society for Contemporary Music.
