Brothers Anton and Lewis Patzner started playing metal violin and cello duets on the street in Berkeley, California in 2002. With Jon Bush on drums, the trio began playing fully amplified. Their sound is progressive and deconstructs heavy rock with nothing more than violin, cello, and drums. The band soon became sought after session players featured on critically acclaimed records from Slash, Pete Yorn, and Taking Back Sunday. In the meantime, Anton even enjoyed a stint in indie rock stalwarts Bright Eyes.
