Even if you don’t normally dig hardcore rock, you should know about the poetic, expansive thinkers and musicians known as Fucked Up. More of an apotheosis than a band, Fucked Up borrow from Buddhism, Henry Darger, the Old Testament, feminism, art nouveau, and so much more. Their singer, a bearded mountain of a man, said in a recent interview: “You want [people] to leave the show feeling like they didn’t waste an evening.” An evening with Fucked Up is never an evening wasted. With Lightning Bolt and Ceremony. (Showbox at the Market, 1426 First Ave, www.showboxonline.com, 6 pm, $10, all ages)
