New Jersey's mathcore stalwarts the Dillinger Escape Plan are set to release their fifth album One of Us Is the Killer on May 14 via their very own Party Smasher label. As noted in SPIN's review of their last shredzpedition, Option Paralysis, the fearless quintet often vacillates between "anthemic crush-and-croon" and "aggro-prog headfucks." The first taste of the new long-player most definitely belongs to that latter category. "Prancer" bursts out of the gate with stuttering Fantômas-style explosions of drums and guitar, before dragging the listener (willingly — the kicking and screaming is a sign that they like it) through an ever-shifting landscape of brutalizing art-metal. Sure, there's one calm moment that sounds like something beamed in from Mr. Bungle's California, but everything else is pounding pistons and bags of glass, not to mention lead screecher Greg Puciato's throat-busting growls and howls. If we were to venture an answer to the forthcoming album's Clue-like titular statement, we'd put our money on that guy.
