Heavy metal is a black-as-night saturation of volume, riffs and attitude. The second annual Shred Fest, happening Saturday, Jan. 2, at the Canal Club, is the creepy crawly embodiment of that all-encompassing onslaught. Featuring the turned-to-11, regional aggressions of Abandon Earth, Seraph, Arcane Haven, Here After, Counter Measures, Attacking Eutopia, I Am the Rapture and Black Acid Ritual, ears will be ringing long into 2016 after the afternoon and night of premeditated attacks. Doors for the heavily stylized and meticulously arranged cacophonies open at 3 p.m. Tickets for the all-ages deafening session cost $10-$12. thecanalclub.com.
