Though legendary rock ‘n’ roll flukes have sometimes had a bit more in them (see Silver Apples), it makes sense that the Monks didn’t–being a pissed-off American GI in 1960s Germany is a circumstance that’s hard to sustain or reproduce. So their debut and sole LP, Black Monk Time, remains sui generis, and really, it’s better that way. The story of this abrasive, inspired masterpiece is natural documentary fodder, and head Monk (abbot?) Gary Burger is in town to answer questions and sign autographs following the premiere of Monks–The Transatlantic Feedback on Saturday at the Chicago Underground Film Festival (see Movies). Now, while the Monks have done the occasional reunion show and are by some interpretations an ongoing concern, Burger has in fact never played in Chicago before; on this trip, though, he’ll do a few songs with masked locals the Goblins. Also on the bill is another CUFF documentary subject, Pittsburgh’s Weird Paul Petroskey, generator of a vast and delirious songwriting oeuvre that includes “Escape the Sneaky Pieman,” “I Don’t Wanna Think About Poking Anything in My Belly Button,” and “Forced Food Deliveries.” Think Wesley Willis without the gravitas or Robyn Hitchcock with a serious head injury. Burger and the Goblins headline, M.O.T.O. plays second, and Weird Paul opens. Sun 8/20, 9:30 PM, Empty Bottle, 1035 N. Western, 773-276-3600 or 866-468-3401, $10.
