Although they never released any records, the Prime Movers were a pivotal band in Southeastern Michigan during the late '60s. Where many of their Michigan contemporaries played straight, frat-house rock & roll, the Prime Movers were a blues band. They were purists, inspired first by classic Chicago blues and then by the Paul Butterfield Blues Band, who proved that white boys could play the blues. Led by brothers Michael and Dan Erlewine, the Prime Movers set out on the same path as Butterfield, playing countless gigs at clubs, frat parties and festivals around the Ann Arbor and Detroit area.
