Hybrid Theory is the debut studio album by American rock band Linkin Park, released on October 24, 2000 through Warner Bros. Records. The album was a huge commercial success, having been certified diamond for sales of over ten million units in the United States alone as of 2010, peaking at number two on the US Billboard 200, and also reaching high positions on other charts worldwide.
Recorded at NRG Recordings in North Hollywood, California, and produced by Don Gilmore, the album's lyrical themes deal with problems lead vocalist Chester Bennington experienced during his adolescence, including drug abuse and the constant fighting and divorce of his parents. Hybrid Theory takes its title from the previous name of the band as well as the concept of music theory and combining different styles.
Four singles were released from the album: "One Step Closer", "Crawling", "Papercut", and "In the End", all of them being responsible for launching Linkin Park into mainstream popularity. While "In the End" was the most successful of the four, all of the singles in the album remain some of the band's most successful songs to date. Although "Runaway", "Points of Authority", and "My December" from the special edition bonus disc album were not released as singles, they were minor hits on alternative rock radio stations thanks to the success of all of the band's singles and the album. At the 2002 Grammy Awards, Hybrid Theory was nominated for Best Rock Album. The album is listed in the book 1001 Albums You Must Hear Before You Die. It was ranked #11 on Billboard's 200 Albums of the Decade. A special edition of Hybrid Theory was released March 11, 2002, a year and a half after its original pressing. The album has sold 30 million copies worldwide. Linkin Park performed the album in its entirety at the Download Festival on June 14, 2014.
