This is a duo album by trumpeter Axel Dörner, who is one of the leading artists on the new Berlin improvised music scene, and no-input mixing board player Toshimaru Nakamura, who garners critical acclaim in the West as well as in Japan. Dörner's playing is far removed from conventional trumpet styles: he constructs his sound mainly from hissing noises, clicks and sputters. Nakamura spins out a delicate electronic sound using only the mixing board's internal feedback. At times they produce sounds one at a time; at others their sounds overlap; and at others, both are silent. The tension and compositional power are stunning. A masterpiece. The album consists of two tracks, each over 25 minutes long, recorded in Berlin in August 2005.
