The Downbeat 5 (not to be confused with Tommy Pollard's Downbeat Five) is a Boston-based rock band started in 1999 by former DMZ guitarist J. J. Rassler and his then-wife, Jen, (who originally used the stage name Ronny Rassler). The band's music draws on 1960s girl group sounds, garage rock, and rougher-edged British Invasion bands like The Rolling Stones.In 2003, the band made it as far as the semi-finals of the 25th annual WBCN Rock & Roll Rumble.
