Canada’s Slagduster are back with their first new material in over 6 years, and they are groovier than ever. Heaviness and stop on a dime time changes a la Meshuggah, SikTh, and Car Bomb are frequently employed by the band, with the vocals maintaining a Mike DiSalvo-like lower mid-range punch. Their new album, “Deadweight,” is slated for a May 5th release, and today we have the privilege of premiering a new song from the album, “Profane Puppet,” which is 4 and a half minutes of obnoxiously bouncy riffage garnished with plenty of artificial harmonics, and that’s…well, that’s just great.
