How do you create a mosaic with just one piece? It seems like an almost impossible task. This piece has to be duplicated and its shape modified in order to create an image. And so the Cologne-based artist and music producer Schäfer begins to work on his composition Mosaik with a single synthesizer tone recorded rather incidentally - and explores its modulation in a variety of ways. By limiting the source material to the maximum, Schäfer allows himself to be artistically challenged and ultimately builds a mosaic from only one piece of sound that is reminiscent of an immersive meditation.

The place of this meditation is the Cologne church John XXIII, in whose echo Schäfer places the finished track. Together we enter the church and only after the first notes have sounded does Mosaik become a sonic space of its own, inviting us to close our eyes and explore its noisy textures. Like passing thoughts, the music flows, undulating sounds wandering through the soundscape. They form chords as if by accident, casual acquaintances of tones binding and unbinding. Mosaik is ambient in the best sense: unobtrusively electronic, peacefully spatial.

After the last note has faded away, the ambient sounds slowly open the eyes of the listener again. Who now inserts the B-side, is led back to the starting point by the backwards sounding Mosaik (rev.): certainly the gentlest way to rewind a cassette.
