Heavy is the hand that shreds, especially in a band with not one, but two brutal drummers like Ancient Sky. “Two Lights” is a slamming single from the Brooklyn psych-rock quintet off the upcoming LP Mosaic, due out June 9th via Wharf Cat Records. Ancient Sky swings back and forth in between doom and drone like a massive pendulum. Though they’ve been lurking in the shadows for a while now with crossovers into other bands like Holy Sons and Dommengang, Ancient Sky shows nothing but brute strength and potential on “Two Lights,” a lumbering, lead-footed kick in the ass.

The record release show for Mosaic is June 6th at Union Pool in Brooklyn.
