The Rock 'n' Roll Rumble (formerly the "WBCN Rock 'n' Roll Rumble"), begun in 1979, is a Greater Boston "battle of the bands" competition sponsored by WZLX and its local music show Boston Emissions. Its predecessors were the Bicentennial Tournament of the Bands held in 1976 at The Club in Cambridge, Massachusetts and co-sponsored by WBCN and Inn Square Men's Bar, as well as 1978's First Annual Spring Rock 'n' Roll Festival co-sponsored by WBCN and the Boston Phoenix.
