LINKIN PARK formed in high school, and it was the addition of second vocalist Chester Bennington that saw them break through into the mainstream. The vocal interplay between Bennington and rapper Mike Shinoda offered a fresh take on the established nu-metal blueprint. 2000's Hybrid Theory was an instant hit, selling 27 million copies. Through the years, the band have continued to push themselves, collaborating with JAY Z on Collison Course and dabbling with electronic new wave sounds on A Thousand Suns.
