Notorious musician/critic/headcase Julian Cope recently wrote that “slow is the new loud.” I’m not entirely certain what that means, but it makes sense in a koan-esque way. It can’t be denied, however, that loud is still the old loud. Recognizing that there is no real substitute for sheer mammoth noise, Part Chimp gleefully keeps the needles in the red on its debut disc, Chart Pimp. Chimp—the latest bucket of hubbub from Ol’ Blighty—captures the kind of sound that might emerge from British exchange students who’ve just been led through the Stooges Wax Museum by members of Mudhoney: a tumult so sludgy and cacophonous that you forget a chorus is due to come back around. But for all the din-mongering, Part Chimp is not a band that takes itself too seriously. Ponder the meaning of tunes such as “SS Mannkuntt” when Part Chimp plays with Mogwai at 8:30 p.m. at the 9:30 Club, 815 V St. NW. $15. (703) 218-6500. (David Dunlap Jr.)
