According to the bio on his website, Matthew Frantz has “resurrected mastodons and several specials of dinosaurs with the sheer power of his guitar.” He’s kidding … we think. But that statement sheds some light on the Chicago-based songwriter’s style. Unpredictable and a little goofy, Frantz trades in a bizarre strain of indie and freak folk that defies easy classification and, judging by the title of his new EP, Fuck the Flies, implies a lively sense of humor. Frantz stops by the Skinny Pancake in Montpelier on Sunday, July 5.
