Doom (swamp, sludge, whatever) metal prophets Thou hit all the right notes with their "The Changeling Prince": riffs that weigh enough to create their own gravitational field, screeching about fractured reality and, most rewarding of all, a chorus that goes: "Behind the mask / Another maaaaask"

The video is an over the top horror gothfest, taped during a recent New Orleans gig. 

"The Changeling Prince" is part of "Magus", out on Sacred Bones 31/08/2018.
