“Thorn, a one-man act from Arizona, used to dwell in the chunky sloth of death/doom with debut Crawling Worship, focusing heartily on concrete-thick slogs and hell-scraping gutturals. Amping the tempo while letting old habits die hard, sophomore effort Yawning Depths offers a beatdown not unlike sole member Brennen Westermeyer’s other brutal deathgrind project Fluids. Borrowing influences from post-metal and doom, it’s a shape-shifting experience that is as relentless as it is meditative.” Sleepy bulldozers.
