People love to mock Canadians for being placid, harmless, and adorable, but that stereotype of our neighbors to the north overlooks one critical fact: While folks from Toronto and Montreal might be peaceful and well-meaning, their neighbors in Vancouver don’t fuck around. Just a few months ago, crazed Vancouverites torched half their otherwise idyllic city after the Canucks lost the Stanley Cup Finals. And historically, Vancouver is a punk-rock town, a fact well explored in Susanne Tabata’s documentary Bloodied but Unbowed. Between 1978 and 1982, the city produced punk acts like Subhumans, The Modernettes, and D.O.A., with its inimitable frontman Joey Shithead. They and others narrate Tabata’s raucous, unvarnished footage alongside American contemporaries, including Jello Biafra and Henry Rollins. Today, Vancouver’s music scene is tragically just one of many of the Great White North’s indie factories. O Canada, God keep your land glorious and free. (Benjamin R. Freed) The film shows at 8 p.m. at Artisphere’s Dome Theater, 1101 Wilson Boulevard, Arlington. $6.


Sonic Circuits, the excellently curated annual festival of experimental music, kicks off tonight at the AFI Silver Theatre in Silver Spring. Local ensemble STYLUS will accompany two silent experimental films—-James Sibley Watson and Melville Webber’s Lot in Sodom and Man Ray’s Emak-Bakia—- using 10 vintage record players and two cellos. 8 p.m. $12.

It’s time for another Moombahton Massive—-the more-or-less monthly showcase of the microgenre created by D.C. DJ Dave Nada—-but this time things are a little different: This time Nada and some of his compatriots in moombahton are facing off against the Bay Area’s Tormenta Tropical DJs, who specialize in cumbia. One holdover from past Moombahton Massives: Nada’s mom will be selling her homemade empanadas. The show is $6. Empanadas are $3.

I really can’t tell you what to expect from tonight’s acoustic Marah show, but feel emboldened knowing this: The alt-country band has made great albums that are raucous and rough-and-tumble (If You Didn’t Laugh, You’d Cry) and great records that are polished and poppy in the Elvis Costello vein. Odds are good it’ll be a treat. 7:30 p.m. at Jammin’ Java. $15.


Best place for some erudite chuckles is Calvin Trillin‘s book event tonight at Politics & Prose. 7 p.m. Free.


The influential modern-dance duo Eiko and Koma perform Regeneration, a sort of mini-career retrospective that includes pieces from 1976, 1984, and 2010. This is very sold out, but maybe this kind of thing has scalpers?
