A red tuba, a white squeeze box, a green Tyrolean hat, lots of lederhosen and a frantic stage show make Winzige Hosen every mother’s favorite punk polka band. Part Frankie Yankovic, part Gogol Bordello, Winzige Hosen is a seven-piece group based in Duluth’s Bavarian Hill country — the place where 2/4 dance steppers collide with stage divers and electric guitars blend with accordions through Marshall stacks. A world stuck in permanent Oktoberfest. The roster features Kala Moria on tuba, Abe Curran and Luke Nyen on guitars, Eric Bong on bass, Patrick Sunderland on trumpet, Tommy Kishida on drums and Brian Schanzenbach on voice and accordion.
