Linkin Park is an American rock band from Agoura Hills, California, formed in 1996. Since their formation, the band has sold more than 50 million albums and won two Grammy Awards. It achieved mainstream success with its debut album, Hybrid Theory, which was certified Diamond by the RIAA in 2005. Its following studio album, Meteora, continued the band's success, topping the Billboard 200’s album charts in 2003, and was followed by extensive touring and charity work around the world. In 2003, MTV2 named Linkin Park the sixth greatest band of the music video era and the third best of the new millennium behind Oasis and Coldplay.

Having adapted the nu metal and rap rock genres to a radio-friendly yet densely-layered style in Hybrid Theory and Meteora, the band explored other genres in their next studio album, Minutes to Midnight. The album topped the Billboard charts and had the third best debut week of any album that year. They have also collaborated with several other artists, most notably with rapper Jay-Z in their mashup album Collision Course, and many others on Reanimation.

In October 2008 Shinoda revealed on his blog that he, Phoenix and Hahn had begun working on two song ideas at Hahn's home, with studio recording to begin in earnest soon. In 2008, Bennington announced that Linkin Park's fourth studio release will be a concept album. The band has not released many specific details about the album. In an interview with MTV in November 2008, Bennington stated, "It sounds a little daunting to me, so, I think my confidence level will drop, but when it was presented to us by this friend of ours, we liked the idea. It was an inspiring idea, and it was something we could relate a lot of the things we like to write about to" He also added that the band planned to begin recording in December for a six-week session. The album was expected in mid 2009, but in late March, Mike Shinoda wrote on his blog saying "We're hoping to have Chester's Dead By Sunrise album out this fall, and the new LP album out early next year."

In December 2008, Digidesign gave the band the opportunity to preview the new Pro Tools 8 software. The experiment resulted in an instrumental song performed by Shinoda and Bourdon.

In April 2009, Mike Shinoda revealed on his blog that Linkin Park will be working on the score for Transformers: Revenge of the Fallen with successful film composer Hans Zimmer. On May 7, it was further confirmed that the song recorded for the film is titled "New Divide," and was released as a single on May 18. A clip from the song can be heard 14 seconds into the new trailer. The music video for "New Divide" was released on June 12, 2009 and was directed by Mr. Hahn. On June 22, 2009, the band played a short set after the premiere of Transformers: Revenge of the Fallen. The concert took play on the street in Westwood Village.

In May 2009, Linkin Park announced that they were working on their fourth album which will be released in 2010, with the aim for it to be "genre-busting". Shinoda also stated recently in an interview with IGN that the new album will have in comparison to Minutes to Midnight a bigger "thread of consistency" and will also be more experimental and "hopefully more cutting-edge". Additionally the band's other vocalist Chester Bennington confirmed in an interview with Taipei Times that Rick Rubin returns as the producer of the new album.
