Quebec has a long history of producing weirdo metal bands, ones that take a sideways approach to otherwise familiar subgenres (see: Gorguts, Cryptopsy, Chthe'ilist). But that tradition mostly started with Voivod. Not many thrash bands can get away with covering Pink Floyd and King Crimson, but Voivod doesn't just cover those bands—those prog-rock influences have always been right on the surface. Their off-kilter arrangements, odd time signatures, and wiry riffs aren't exactly standard circle pit fodder, but they produced classics like 1987's Killing Technology. Voivod just released the Post Society EP, and three decades in, they're still wonderfully weird. MATTHEW W. SULLIVAN
