Certain indie-rock tastemakers (OK, Pitchfork) have likened Portland’s Blitzen Trapper to defunct darlings Pavement, a comparison the scrappy sextet occasionally lives up to. Like its vaulted predecessors, Blitzen Trapper’s free-range melodies and haphazard guitar action evoke the ambience of a charmingly cluttered teenage bedroom, a place where vintage rock tees and stale pizza can peacefully coexist. The group’s mid-fi sound is hardly the stuff of revelation, but its willful forays into country-rock help distinguish it from a legion of semi-pro slackers with cheap guitars and copies of Slanted and Enchanted. Acoustic twang jacked from American Beautynera Grateful Dead runs alongside effervescently insouciant pop-rock; the result is a bit like mixing organic granola with fizzy orange soda. Or maybe Pabst and patchouli. Blitzen Trapper performs with Two Gallants and Songs For Moms at 9:30 p.m. at the Rock and Roll Hotel, 1353 H St. NE. $10. (202) 388-7625.
