Hailing from pissed-off Pennsylvania, local punks Mischief Brew, cook up a riot like nobody’s business. Between frontman Erik Petersen’s antics and punk-folk riffs, this Philly collective knows how to keep it fresh. Mischief Brew’s mix of marimba and mandolin bring to mind Eastern European street parades, or a less sophisticated Gogol Bordello. With the DIY aesthetic that Against Me! now lacks, Petersen along with his bandmates crank up the volume with tracks like, “Fight Dirty”, and “A Liquor Never Brewed”. Think the summer of ‘77, Mischief Brew is punk as fuck. They’ll be taking the stage with the garden state surf punks Mirrors and Wires. Leave your studded belts at home.
