In just over a year, Boston-based indie rock band Speedy Ortiz has gone from headlining the quaint, tiny Black Cat backstage to taking over the cavernous main stage. The group’s quick rise to prominence makes sense: Speedy Ortiz’ singer and guitarist (more like shred-master) Sadie Dupuis is one of the best songwriters of the past few years, the rare lyricist who can balance acid-tongued wit with tender emotionality. “Laugh out of habit at the lump schematics/ I smoked my senses, it made me so demented,” she sings on “Tiger Tank” from 2012’s debut Major Arcana, her voice bearing the same brand of slacker indifference that made Stephen Malkmus everyone’s rock ‘n’ roll hero. But unlike the complacent, 21st-century Malkmus, Dupuis almost never falls into the trap of ironic detachment. As the band’s, uh, speedy transition from backstage to mainstage and its exciting new LP, Foil Deer, tell us, Speedy Ortiz still has plenty of old-fashioned spunk. May the band stay “slanted and enchanted” forever. Speedy Ortiz performs with Krill and Two Inch Astronaut at 7:30 p.m. at the Black Cat, 1811 14th St. NW. $15. (202) 667-4490. blackcatdc.com.
