NACHZEHRER From beerhall ska-punk to bruiser hardcore like Death Before Dishonor, Boston’s hard-edged bands have a respectable tradition of raucous, take-no-prisoners pummel-and-shout. Nachzehrer applies the aggression historically associated with this northeastern city to black metal — peeling the genre’s increasingly transcendental elements back to reveal a dark, furious heart. Broken-glass vocals rasp and grate in a stew of blast beats and guitars that swing from punk-metal chug to the downtuned, pagan palette of Norwegian originators. Nachzehrer is a band of respectable endurance, too: these cuts may have the speed and fury of Northeastern hardcore, but they’re at least twice as long. These marathons of godless fury, then, are supposed to wear you down — reducing you to a moshing ball of nihilism and burned-out synapses. To some of us, this sounds like a good time! With Martyrvore, Death Shroud, and Admiron Sphere. $7-$12. Sept. 27, 9 p.m. The Milestone, 3400 Tuckaseegee Road. 704-398-0472.
