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.

"The group drive furiously into the promise of freedom offered by improvised music to build their own unpredictable edifice. if there's a lesson to be drawn, it's that borbetomagus's focused, lateral expansion is an endlessly fertile plane in itself, regardless of the specifics of form. Mertens's film deftly navigates this idea without ever being overly prescriptive or sentimental. By allowing the work and its ambiguities to stay firmly in the foreground, any conclusions about how to evaluate the music are left up to the audience. Borbetomagus have always thrived on precisely this physical and conceptual interaction. The questions are the answers and vice versa, like two bells locked together." (Matt Krefting, The Wire)
