Krallice + Vaura + Psalm Zero + MV Carbon

As heard on their fourth LP, 2012's Years Past Matter, Krallice continues to defy easy extreme-metal taxonomy. Tonight the local standouts air their gnarled, transporting riff fests in the ’Burg, with help from Vaura—which offers potently melancholic gloom rock with wiry prog-metal undergirdings—the Extra Life–Castevet spin-off Psalm Zero and experimental cellist-composer MV Carbon.
