Magrudergrind’s controversial two-month-old release—Crusher, on the new Scion A/V label—is the sound of a heart attack: Twelve intense minutes that effortlessly bridge the gap between D.C. hardcore and Napalm Death-style grindcore. Haters will hate, but corporate bankrolling does nothing to diminish the local trio’s anti-establishment, anti-gentrification, defiantly left-wing political thrust on this six-song EP. After teasing its affinity for old-school hip-hop with record-scratching and random shout-outs to the “202” on 2009’s self-titled full-length, Magrudergrind flips the script and goes full-on b-boy on “Heaviest Bombing.” Frontman Avi Kulawy absolutely kills it on his jazzy, syncopated verse; more recombinant genre-bending would be welcome on future releases. As for the rest of Crusher, everyone else in the DMV’s extreme music scene will be spending 2011 just trying to catch up.

MAGRUDERGRIND PERFORMS WITH LEMURIA, PULLING TEETH, GIVE, AND HOT MESS AT 7 P.M. AT ST. STEPHENS CHURCH, 1525 NEWTON ST. NW. $8 -$10. (202) 232-0900.
