Mischief Brew was an American band from Philadelphia, Pennsylvania, United States, which played 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 drew 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. Petersen’s lyrics often pay homage to American labor radicalism of the early 20th century. Mischief Brew has released albums and EPs on many different labels, notably Art of the Underground, Gunner Records, and Fistolo Records. In support of these records, Mischief Brew has toured extensively throughout the United States and Europe. When playing live, they have performed with four to five people, incorporating such instruments as junk/found percussion, trumpet, accordion, violin, mandolin, and vibraphone into their set.
