The most reliably bone-crushing band from Poland, Behemoth have progressed over the years from black metal toward death metal. And they've done it their own way—devoted to the horned lord of the fiery underworld by all his names, they also explore paganism's dark historical corners. Their meticulously produced sound is just as nuanced: Sitars, synthesizers, and acoustic guitars that temper the chaos make it even more evil, as does their willingness to slow down and let the full-force attack sneak up on you.
