"shift #1" is a collaboration album by the two drone/ambient artists rsn and N. the album comprises three songs that deal with semitone shifts, creating an aesthetic depth of sound on the one hand and building up a long arc of tension on the other. "shift #1" is a musical colossus - sound, structure and length create an immersive sound experience. quiet, rather contemplative sounds gradually develop into an alert sound construct. sometimes, however, it remains calm and inward-looking, meditative and floating. what is special here are the drones that are consistently thought through to the end, which manifest themselves over the course of the 20-minute compositions and only allow a minimal shift. initially ambient surfaces are overlaid piece by piece to change from calm and silence to dissonance - but this happens almost imperceptibly.
