After years of toiling in relative obscurity, this Denver ethnic-folk/indie-rock quartet is enjoying some buzz, thanks in part to their appearance on the Little Miss Sunshine sound track. Their raucous but mellifluous take on vintage cabaret music and Gypsy jams, combined with their wanderings through Latin traditions, makes them allies of Gogol Bordello, the Dresden Dolls, and Calexico--all of whom they've shared stages with--and their playful devotion to classic underground rock makes them a natural club act (a slot at this year's Bonnaroo notwithstanding). Their 2004 album, How It Ends, is their most recent batch of originals, but early this year they released Curse Your Little Heart (Ace Fu), a six-song EP with five covers, including a traditional mariachi tune, Frank Sinatra's "Somethin' Stupid," and the Velvets' "Venus in Furs." I've never heard anybody cover "Venus in Furs" properly--not even the Creatures when they had John Cale playing electric viola--but Devotchka comes within a few whip strokes. My Brightest Diamond opens. a 9:30 PM, Logan Square Auditorium, 2539 N. Kedzie, 773-252-6179 or 866-468-3401, $14, 18+.
