about

Between 1989 and 1994, Dieter Mauson and Siegmar Fricke ventured into uncharted sonic territory under the name Delta-Sleep-Inducing Peptide (DSIP). Their work explored the boundaries between consciousness and slumber, sculpting sound narratives that mirrored the stages of sleep itself. During this period, DSIP released over 25 cassette albums across international labels, each one a fragment of their analogue dreamscape, recorded in various home studios around Germany.

Now, for the first time, three of their seminal works, “Somnosections” (1990), “L-Tryptophan” (1991), and “Pre-Natal” (1994), are brought together in a box set, revisiting the duo’s groundbreaking 1990s period (the duo regrouped in 2013-2018). These recordings stand as timeless documents of creative intuition, recorded with tactile precision on multi-track tape machines, analog synthesizers, samplers, drum units, and Dictaphones. Local radio and television fragments, repurposed as sonic material, weave through these pieces to form the distinct fabric of the DSIP sound world.

What makes DSIP’s music exceptional is its profound sense of organic flow. Despite its heavily electronic origins, it breathes with a strange, almost subconscious vitality, a transparency that goes beyond intellectual analysis. It doesn’t ask to be understood, it is felt. Listeners are drawn into an experience that transcends mere ambience. It is immersive, hallucinatory, and deeply psychic.

Each recording represents a different portal into DSIP’s universe. “Somnosections” is mystical and seductive, shifting between dark, Lynchian atmospheres and driving rhythmic patterns. “L-Tryptophan” is an unfolding journey, 44 minutes of immersive, mind-expanding waveform bliss. Pre-Natal ventures deeper still, looping hypnotic arpeggios and textures into an early vision of hauntology, dreamlike sound before the term or The Caretaker even existed.

Across two and a half hours of alien, otherworldly sound, DSIP reveal that their music neither belongs to this world nor seeks to. It is as natural as it is supernatural. A sonic landscape shaped by intuition, emotion, and the liminal space between waking and dreaming.
