Green Day is an American punk rock band formed in 1987. The band consists of lead vocalist and guitarist Billie Joe Armstrong, bassist and backing vocalist Mike Dirnt, drummer Tr Cool and guitarist and backing vocalist Jason White, who became a full member after playing in the band as a session and touring guitarist for 13 years. Cool replaced former drummer John Kiffmeyer in 1990, prior to the recording of the band's second studio album, Kerplunk (1992).
Green Day was originally part of the punk scene at 924 Gilman Street in Berkeley, California. The band's early releases were from the independent record label Lookout! Records. In 1994, its major label debut Dookie released through Reprise Records became a breakout success and eventually sold over 10 million copies in the U.S.
Green Day was widely credited, alongside fellow California punk bands Sublime, The Offspring and Rancid, with popularizing and reviving mainstream interest in punk rock in the United States. Green Day's three follow-up albums, Insomniac (1995), Nimrod (1997), and Warning (2000) did not achieve the massive success of Dookie, though they were still successful, with Insomniac and Nimrod reaching double platinum and Warning reaching gold status. The band's rock opera, American Idiot (2004), reignited the band's popularity with a younger generation, selling five million copies in the United States. The band's eighth studio album, 21st Century Breakdown, was released in 2009 which achieved the band's best chart performance to date. In 2012, 21st Century Breakdown was followed up by a trilogy of albums called Uno!, Dos!, and Tr! released on September, November and December 2012 respectively.
They are one of the worlds best-selling groups of all time, having sold over 75 million albums worldwide. The group has won five Grammy Awards: Best Alternative Album for Dookie, Best Rock Album for American Idiot, Record of the Year for "Boulevard of Broken Dreams", Best Rock Album for the second time for 21st Century Breakdown and Best Musical Show Album for American Idiot: The Original Broadway Cast Recording. In 2010, a stage adaptation of American Idiot debuted on Broadway. The musical was nominated for several Tony Awards, including Best Musical and Best Scenic Design.
