Linkin Park was named as Hybrid Theory in their earlier guise for their unique rap-metal crossover styles—and they retained the moniker for their debut album for good. Needless to say, singer Chester Bennington and rapper Mike Shinoda make a dynamite of an unconventional combination along with the band's cutting-edge sound. Hits like "Crawling", “One Step Closer”,”Papercut" and "In the End" propelled these California natives to the top of the charts, selling millions of copies and winning them the Grammy Award for Best Hard Rock Performance that year. Do we need say more than Hybrid Theory is a crossover keeper? Hit play.
