From Philadelphia, Pennsylvania

From last.fm:

Mischief Brew is an Anarchist folk-punk band. It is a wicked concoction by Erik Petersen – a musical feast falling somewhere between the categories of pirate punk, Celtic folk, gypsy swing, devilish jazz, American olde-tyme and country. It’s good music to stomp, kick, pogo, jitterbug, waltz, drink, twist and shout to – whether the performance is solo acoustic or with a backing band of accordion, drums, and mandolin.
