The album “Kontraktion” is the result of two long sessions that have been recorded on tapes by Conrad Schnitzler and Siegmar Fricke in Con’s former studio Leberstrasse in Berlin. The five soundscapes (produced in November 1986 and July 1987 with EMS-Synthi A, KORG MS 10+20, delays) contain all the machinistic energy and infernal industrial sound-eruptions similar to Conrad’s first three albums “Schwarz”, “Rot” and Blau” and to the rumbling train-wheel-rhythms of “Zug” (from the CON-album 1978). In addition “Kontraktion” carries the spirit of the first album by Cluster (released on Philips in 1971) due to the imposing bruitiste elements of uneasy sci-fi atmospheres. In 2014 the long sessions on tape have been edited, restructured and recombined by Siegmar Fricke at Pharmakustik-studio Germany and have now become a powerful milestone…30 years after they have been recorded.
