Ostensibly a concept album about Jesus' stillborn but now quantum-leaping twin brother (not that you'd ever figure that out by listening, of course), De Vermis Mysteriis marks a respectably ferocious sixth installment for Oakland's now-venerable post-sludge/post-thrash institution. There's a musicianly instrumental that breaks levees; a musket-firing war-march closer; some big-boned, bog-drowned late-Motörhead roaring. And maybe the two strongest constructions – seven-minute lunch-bucket lurcher "Madness of an Architect" and wild-dog stomp "Romulus and Remus" -- open with buzzing white noise.
