Borbetomagus: A Pollock of Sound is the first feature-length documentary about the legendary improv / noise group Borbetomagus. Filmmaker Jef Mertens brings a raw, urgent, and unpolished vision focusing on a band that has spent almost four decades defining and redefining not just their music, but the boundaries of music itself. Band members Don Dietrich, Donald Miller, and Jim Sauter tell their story with the help of artists, writers, photographers, and filmmakers that include noted critic Byron Coley, drummer Chris Corsano, guitarist Thurston Moore, groundbreaking Japanese noise unit Hijokaidan, and Switzerland's masters of "cracked electronics," Voice Crack. Includes never-before-seen archival footage, amazing photographic finds, and previously unreleased recordings.
