Although rooted in alternative metal, Linkin Park became one of the most successful acts of the 2000s by welcoming elements of hip-hop, modern rock, and atmospheric electronica into their music. The band's rise was indebted to the aggressive rap-rock movement made popular by the likes of Korn and Limp Bizkit, a movement that paired grunge's alienation with a bold, buzzing soundtrack. Linkin Park added a unique spin to that formula, however, focusing as much on the vocal interplay between singer Chester Bennington and rapper Mike Shinoda as the band's muscled instrumentation, which layered DJ effects atop heavy, processed guitars. While the group's sales never eclipsed those of its tremendously successful debut, Hybrid Theory, few alt-metal bands rivaled Linkin Park during the band's heyday.
