After a decade of hair bands singing about wild times and fast living, hard rock in the ’90s turned darker, heavier, and meaner. This can be credited to the commercial success of a wave of bands emerging from outside the mainstream. Metallica’s bulldozing arena anthems reflect their thrash-metal roots; Nirvana’s grunge revolution delivered the angst of underground rock to MTV; Rage Against the Machine’s politically charged attacks reflected their days in the hardcore scene; and Tool’s harsh nihilism grew out of the fringes of alt-metal. Outside of Guns N’ Roses, who managed to score some awfully big hits early in the decade, few veteran pop-metal acts survived these seismic shifts. It wouldn’t be until the tail end of the ’90s that a brash young MC from Detroit calling himself Kid Rock would help revive high-volume party music with his infectious mix of swaggering rock riffs and megaton hip-hop beats.
