As one of the pioneers of US metalcore, Converge team up with Japan's heaviest sludgecore band, Hellchild. Converge offer up an original track, a cover of Depeche Mode's "Clean", and three live tracks. Hellchild then rage into a rabid frenzy with four songs produced by Billy Anderson. Their material showcases both their intense energy and their blinding heaviness, and includes their version of "Insurrection Of The Living Damned" originally by Bulldozer.
