Surprisingly, Arms doesn't come stomping right out of the gate -- "Stone Breaker," the album's opener, cruises hazily in on a wave of organ and psychedelic guitar before the Southern thrash riffs begin to roar and crunch. Each of the album's 12 tracks is a forceful gut-punch, with plenty of bass in the mix to juice the already hip-swingin' grooves. C.O.C. has been mixing Southern rock with metal for a couple of decades, and it's mastered its particular sound at this point. Special attention must be paid to the swinging drums, courtesy of Galactic's Stanton Moore. Only Pepper Keenan's still-rudimentary vocals, which no amount of computer filtering can mask, are a drag. Five years between studio albums is too long for a band this powerful.
