With three celebrated heavy music stalwarts at its helm (Aaron Turner, Brian Cook and Nick Yacyshyn), Sumac delivered the perfect record for a post-Isis, post-Hydra Head world in 2015. Titled The Deal, this massive six-track powerhouse deserved all of the accolades it received upon its release. The record navigated familiar waters, but with a new vessel. These behemoth compositions presented an interesting take on post-metal and sludge that was rhythmically complex, experimental, semi-improvisational and most importantly, destructive. The Deal seemed to combine the best moments from its creators’ past work into a monolithic sound that will now be associated with Sumac and Sumac alone.
