Conrad Schnitzler (1937-2011), composer and concept artist, was one of the most important representatives of Germany's electronic music avant-garde. A student of Joseph Beuys, he founded Berlin's legendary Zodiak Free Arts Lab, a subculture club, in 1967/'68, was a member of Tangerine Dream (together with Klaus Schulze and Edgar Froese) and Kluster (with Dieter Moebius and Hans-Joachim Roedelius), and released countless solo albums. Pyrolator, born Kurt Dahlke in 1958, cofounder of the legendary German label and publisher Ata Tak, member of various seminal post-punk bands including D.A.F. and Der Plan, has released solo albums under his artist name from 1979 on. The Con-Struct series has it's roots in Schnitzler's daily excursions through the sonic diversity of his synthesizers. Finding exceptional sounds with great regularity, he preserved them for use in subsequent live performances and amassed a vast sound archive. When the Berlin-based m=minimal label reissued two Conrad Schnitzler albums in 2010 and '11 (MINIMAL 001 LP, MINIMAL 004 LP), label honcho Jens Struver was granted access to this audio library.
