Limp Bizkit made their reputation through hard work, touring the hell out of their debut album Three Dollar Bill Y'All and thereby elevating themselves to the popularity status of their similarly rap-inflected, alt-metal mentors Korn. With their second album, Significant Other, they come close to reaching Korn's artistic level; at the very least, it's considerably more ambitious and multi-dimensional than Three Dollar Bill. Limp Bizkit, of course, hasn't abandoned their testosterone-overloaded signature sound, they've just built around it. There are flourishes of neo-psychedelia on pummeling metal numbers and there are swirls of strings, even crooning, at the most unexpected background. All of it simply enhances the force of their rap-metal attack, which can get a little tedious if it's unadorned.
