We’ve been telling you about Keith Merrow’s death metal side project Demisery for months now, and we’ve even given you a sample of what the album has in store. Today we give you the exclusive premiere of Hive of Mutation in full, evil riffs, searing solos, churning blast beats, bowel-rumbling death growls courtesy of Gord Olson, and all. You all should know by now that Merrow can work his way around a guitar, but that he’s able to execute a death metal record so well — with songs and riffs that actually stick in your brain, no less — shows just what a master of modern metal he is. Click “play” and let the grimness wash over you, then head over to Keith Merrow’s website to pre-order the record, which comes out on November 14th.
