Originally consisting of three high school friends, Linkin Park’s foundation was anchored by Mike Shinoda, Brad Delson, and Rob Bourdon. After graduating from high school, the California natives began to take their musical interests more seriously, recruiting Joe Hahn, Dave "Phoenix" Farrell, and Mark Wakefield to perform in their band, Xero. Though limited in resources, the band began recording and producing songs within Shinoda’s make-shift bedroom studio in 1996. Tensions and frustration within the band grew after they failed to land a record deal. The lack of success and stalemate in progress prompted Wakefield, at that time the band's vocalist, to leave the band in search of other projects. Farrell also left to tour with Tasty Snax and other bands.
Linkin Park released Hybrid Theory on October 24, 2000. The album, which represented half a decade’s worth of the band’s work, was edited by music producer Don Gilmore. Hybrid Theory was a massive commercial success; the band sold more than 4.8 million records during its debut year, earning it the status of best-selling album of 2001, while singles such as "Crawling" and "One Step Closer" established themselves as staples among alternative rock radio play lists during the year. Additionally, other singles from the album were featured in movies such as Dracula 2000, Little Nicky, and Valentine. Hybrid Theory won a Grammy Award for Best Hard Rock Performance (for "Crawling") and was nominated for two other Grammy Awards: Best New Artist and Best Rock Album. MTV awarded the band their Best Rock Video and Best Direction awards for "In the End". Through the winning of the Grammy for Best Hard Rock Performance, Hybrid Theory’s overall success had catapulted the band into mainstream success.
Both Hybrid Theory and Meteora combined the alternative metal, nu metal, and rap rock sound with influences and elements from hip-hop, alternative rock, and electronica, utilizing programming and synthesizers. William Ruhlmann from Allmusic regarded it as "a Johnny-come-lately to an already overdone musical style," whereas Rolling Stone called "Breaking the Habit" "risky, beautiful art".
In Minutes to Midnight the band experimented with their established sound and drew influences from a wider and more varied range of genres and styles, a process Los Angeles Times compares to a stage in U2's work. In it, only two of the songs feature rapping, and the majority of the album can be considered alternative rock rather than nu metal or rap rock. It is also their first studio album to feature guitar solos.
