A project launched by Tim Spelios and David Weinstein in the 80s, Impossible Music features cutup, montaged, recycled material, lopsided grooves, appropriated, restored, or reconstituted audio, new and legacy technologies, loops of contrasting and colliding musics, sound effects, disembodied vocal tracks, and noise merged into panoramic constructions.
