After essentially inventing post-punk with a series of jagged and jittery buzz-saw-blast albums in the early '80s, Massachusetts's Mission of Burma amicably called it a day in 1983, and shockingly reconvened 19 years later. While a group so critically lauded could be forgiven for merely mounting a nostalgic cash-grab reunion and touring off old tunes, MoB have done exactly the opposite, releasing four new full-lengths in the decade since their reformation. Their latest, this year's Unsound, finds the quartet as ferocious and fighting-trim as ever, still blending surprisingly melodic serrated-edge riffs with innovative tape loops and adding welcome new wrinkles like out-of-left-field trumpet blasts. With Porcupine. 21+, $20, 8 p.m. 400 Cedar Ave. S., Minneapolis, 612.332.2903.
