Music as composed sound: echoes, artefacts, disturbances and unexpected noises move to the foreground, while melody and rhythm recede. Listening becomes an active, shifting act of decoding – a shared process in which meaning is never fixed, but constantly renegotiated between the ear and the world. At Three Skies, percussionist Dirk Rothbrust, a central figure of contemporary music and member of Ensemble Musikfabrik, and electronic musician Jan St. Werner, co-founder of the pioneering Cologne duo Mouse on Mars, push sound to its perceptual limits. Acoustic and electronic sounds collide, overlap and transform. Rhythms condense, fragment and dissolve; sonic identities disintegrate. Fleeting microseconds – the instant before a sound can be clearly recognised – are magnified and hurled into the space in explosive, microscopically processed bursts. The result is an ever-changing soundscape in which reflections, resonances and disturbances activate the room itself as a living instrument.
