Mischief Brew is a band from Philadelphia which plays DIY anarcho-punk music, incorporating a variety of styles including American folk, swing, and Gypsy-punk. It was started by Erik Petersen as a solo project, but eventually grew into a band. Petersen draws inspiration from the protest movements of the 1960s, "the idea that rebellion in music didn't originate in punk rock" (Profane Existence No. 54, 2007), and anti-establishment artists like Woody Guthrie and Crass.
