His early projects focused on noise (Blumm's way of rebelling against the classical guitar), but his work became more structured once he became interested in radio plays. A move to Berlin in 1997 found Blumm collaborating more, most notably with Harald "Sack" Ziegler for the Sack & Blumm project, and his radio plays were being broadcast across Germany. Having already released records on the Staubgold, Gefriem, and Audio Dregs labels, Blumm came to most people's attention in 2001 when he released Mondkuchen, one of the only "acoustic" records on the generally electronica-leaning Morr Music. In 2002, Staubgold released his dreamy Ankern album, but he returned to Morr for 2005's Zweite Meer and 2006's Summer Kling (Audio Dregs also issued Lichten in 2005). ~ David Jeffries
