The WBCN Rock 'n' Roll Rumble, begun in 1979, is a Greater Boston "battle of the bands" competition co-sponsored by WBCN-FM and its local music show Boston Emissions.
The Rumble in its current form begins in April with a week of preliminary rounds of 24 total bands, as selected by WBCN. The prelims take place on Sunday through Tuesday and Thursday through Saturday, with Wednesday as a "Day of Rest." Each night, four bands play a 30-minute set and are judged by a rotating selection of representatives from the Boston music industry. A winner is announced at the end of the night.
Each night's winner moves on to the semi-finals the following weekend, with two wildcard bands rounding out the top 8. The two semi-final winners are joined by one wildcard band for the final round the week after that. A special guest, often a national touring band or a previous Rumble winner, headlines the finals while the judges come to their final decision.
