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 19 years of silence a brandnew studio-album entitled “Narkoklang” has been produced after DSIP’s reactivation in 2013. “Narkoklang” contains six sonic movements of very narcotic nature, arranged in complex stereoacoustic fields of floating ambient spheres, micro-organic particles and pulsating rhythm-oscillations. A highly meditative and intense work, exploring the effects of deep + subliminal sound-morphing during the aural process.
