Critical reception
Radio.com described the song as "[A] thunderous track, with typically anthemic death metal roars and technical, furious percussion." Loudwire said about the song "‘Sarcastrophe’ showcases the songwriting skills Slipknot bring to their recordings. After two decades of shredding through the metal world, the band certainly understands the art of crafting both songs and albums. ‘Sarcastrophe’ could be presented as Exhibit A to back up that claim, as the new cut exposes absolutely no cracks throughout its runtime. Vocalist Corey Taylor sounds as murderous as ever, guitarists Jim Root and Mick Thomson stack layers of guitar parts filled with personality, DJ Sid Wilson scratches at just the right moments and the act's new drummer shows off his death metal chops once again with furious blasting." Music Times said "The brutal song is one more piece of evidence that Slipknot's fifth studio album is going to be one thrashing affair."
