Skid Row was one of the last hair metal bands to hit the mainstream before grunge took over in the early '90s; they were also arguably the last of such bands to exhibit much originality. While the band's 1989 self-titled release employed standard pop-metal riffs and generic lyrics (albeit to great commercial success), 1991's Slave to the Grind and 1995's Subhuman Race broke away from the pop-metal mold with uncharacteristically hard, thrashy guitars and unique songwriting while still relying on varying '80s metal formulas. Though personal differences and changing trends would eventually tear the core lineup apart by 1996, Skid Row showed a tremendous amount of promise during their short time in the spotlight.
