Down is the New Orleans sludge-metal supergroup led by Pantera’s Phil Anselmo and Corrosion Of Conformity’s Pepper Kennan, and later this spring, they’ll release their new EP Down IV – Part Two. The first track we’ve heard from it is a titanic, bludgeoning deep-head-nod groove called “We Knew Him Well,” and it’s gloriously messy but locked-in in the way that only New Orleans metal bands can pull off. Listen to it below.

The self-released Down IV – Part Two is out 5/13.
