Demon Hunter overwhelm ears with their soul-invigorating heaviness, but the high-decibel-blasting Christians also enjoy stacking their albums with meticulous arrangements. “Artificial Light” spreads neoclassical fret-work across thrashy rhythms, while the symphonic “Sixteen” wraps raspy screams in angelic strings. The tempo-shifting “Incision” opens up with passionate swells and vocal harmonies heard in old-school hard-rock ballads.
