Old-school hip-hop, traditional classic rock, and spooling electronic vibes were the initial factors behind the building of the alternative metal quintet, Linkin Park. The band's southern Californian musical roots were also an underlying basis, for drummer Rob Bourdon, guitarist Brad Delson, and MC/vocalist Mike Shinoda formed a tight friendship while still in high school. Shortly after graduation, art student and DJ Joseph Hahn hooked up with Shinoda to make Linkin Park a working four-piece. Singer Chester Bennington was the last piece added to the puzzle, and soon the band became a noticeable face at the Whisky. Linkin Park released their debut album Hybrid Theory in fall 2000, showcasing their likes for fellow alternative acts such as the Deftones, the Roots, Aphex Twin, and Nine Inch Nails. The Dust Brothers also collaborated on the record, as well as producer Don Gilmore (Pearl Jam, Eve 6, Tracy Bonham). -- MacKenzie Wilson, All Music Guide
