Rap metal bands institute the vocal and lyrical form of hip hop. Examples of rap metal include Crazy Town, Clawfinger, Stuck Mojo, Skindred and Rage Against the Machine. The thrash metal band Anthrax also helped pioneer the genre. Rap metal is often mislabeled as rapcore (a genre which fuses hardcore punk with hip hop) or nu metal, a genre which has similar elements in the music, rap metal usually does not include turntables or sampling into its sound, although keyboards are often used. Rap metal bands, unlike nu metal bands, are almost always fronted by rappers. Rap metal also lacks the melodic singing and growling commonly associated with nu metal.
