Vocalist CJ McMahon’s exit from Australian deathcore band Thy Art is Murder turned out to be a short one, as about one year later, he announced his return. You’ve even gotten a chance to hear a new song from the band with their singer in place. He rejoined the  band for the Unify festival, and some professionally-shot footage of the singer back in the  band performing “Holy War” has surfaced via Unify’s YouTube page. McMahon and the  band sound great, and it’s pretty easy to see why they welcomed him back in the band.
