Imagine Mastodon. Imagine their technical ability and prowess in all their hairy, B-movie tattooed, Star Wars fan-boy glory. Now imagine Leatherface from The Texas Chainsaw Massacre shows up and you have Blue Ox. Minneapolis’ sludge quintet are unrelentingly heavy, punching hard enough to make brick walls bleed and playing fast enough to make greyhounds depressed. Night of the Technicolor Yawn is the pinnacle of this in full effect. Truly bludgeoning riffs pile up one after the other whilst vocals are screamed hard enough at you, you start melting, all at literal breakneck speed. If Blue Ox took prisoners, you can expect them to be executed with an axe as their sophomore Stray Dogs On Pity Party Island, is a savage animal on the loose.
