The windshield-rattling bass lines of most Excision tracks sound like Bernie Worrell's bottomed-out Minimoog from Parliament pumped through the UFO sound system in Close Encounters of the Third Kind. It's a buzz so momentous and melodic, it doesn't need rap vocals to be menacing or interesting, though the young Canadian dubstep DJ has dabbled in hip-hop remixing with collaborator Datsik (on last year's Wu-Tang Meets the Indie Culture Vol. 2: Enter the Dubstep). Fans of M.I.A.'s chopped up Sleigh Bells riff on "Meds and Feds" might notice a similarly metal heaviness here dipping into dub, though Excision can as easily whip his guitar crunch into a drum-'n'-bass frenzy—it's all gangster to him. With Vaski, Nick Wishard, Bogtrotter, and Smilodon & Toffler. 18+.
