subgenre of heavy metal music. Nu metal and the related genre rap metal represented a fusion of heavy metal instrumentation and hip-hop conventions such as rapped lyrics and “turntabling.”

Nu metal built on rap metal's foundation of rock and rap collaboration, but it emphasized some of the more aggressive elements of its musical forebears. Intense and angry lyrics, off-pitch guitars, and heavily amplified beats were typical of nu metal songs. The genre was represented most popularly by the bands Korn, Limp Bizkit, Slipknot, the Deftones, Evanescence, and Linkin Park. The American music producer Ross Robinson is often credited with helping bring nu metal into the mainstream and onto radio station playlists.
