Joker Nies [electronics & omnichord] and Hans Schneider [double-bass] live and interdisciplinary with painter Marcus Heesch at ZETTEL'S TRAUM in Leverkusen on 2nd of September 2012. Well, the camera faded out after 15 min., so the missing footage is substituted with a close-up moving over the painting...
