DELTA-SLEEP-INDUCING PEPTIDE (DSIP) was founded in 1989 by Dieter Mauson + Siegmar Fricke. Until 1994 DSIP produced around 25 cassettes, published on various tape-labels all around the world and on the privately run DSIP-cassette-label. The music was recorded with electronic equipment on analogue tape-recorders and cassette-decks in their own homestudios in Hamburg, Mainz and Wilhelmshaven/Germany. DSIP exclusively concentrated on the realisation of experimental + subtle soundtracks which can be described as mind-cinema of the subconscious. The stages of sleep + phenomena of dreams have been musically explored in an idiosyncratic sound-approach. After DSIP's reformation in 2013 and the production of two new albums, OSCILLOPSIA has been produced in the beginning of 2014 and can be characterized as the most complex elaboration by the duo so far. Entirely recorded and mastered on new equipment, OSCILLOPSIA marks a new direction in DSIP's discography by integrating analogue modulations and transformed rhythmic constructions interacting within the cosmic radius of the stereo-panorama. An intense and well-structured sculpture of very psychoactive atmospheres full of internal tension, dynamics and dramaturgical perspectives.
