It's time to stretch the boundaries here, and review a state-of-the-art metal track. (If metal isn't your bag, you may want to come back later for something different.) Oakland's Machine Head qualify as a band of grizzled veterans of the metal scene, having begun pummeling a practice room all the way back in 1991. The band's seventh album, Unto the Locust, finds them firing on all cylinders, and this particular cut is a tour de force of several classic and current metal styles woven from bits that sound like vintage Pantera, vintage Slayer, and some of the proggier metal acts such as Queensrÿche. However, I don't mean to say this is a pastiche. It's a fiercely original, wholly satisfying headbanger, and one of the best metal tracks I've heard all year.
