In 2000, the world was introduced to Linkin Park's debut album, "Hybrid Theory," which quickly became a cultural phenomenon. Hybrid Theory was actually the original name of the band until they had to change it because of a Welsh electronic group called Hybrid. The album's unique blend of rock, rap, and electronic music helped to usher in a new era of nu-metal and catapulted the band to international fame and has become a favourite album for teenagers around the world.
