What happens when you combine the talents and sounds of two heavy weight ambient-drone-progressive-black metal bands like Sunn O))) and Ulver? Magic. Pure bliss. A creeping, hypnotic journey to the darkened nether worlds. Or...just a really bitchin' record. "Terrestrials" will be out next week via Southern Lord Records. Listen to a sample from "Eternal Return" below and go grab the album from the bands here.
