Green Day is an American rock band formed in 1986 by lead vocalist and guitarist Billie Joe Armstrong and bassist Mike Dirnt. For much of the band's career, they have been a trio with drummer Tré Cool, who replaced John Kiffmeyer in 1990 prior to the recording of the band's second studio album, Kerplunk (1991).
Green Day was originally part of the punk scene at the DIY 924 Gilman Street club in Berkeley, California. The band's early releases were with the independent record label Lookout! Records. In 1994, their major label debut Dookie, released through Reprise Records, became a breakout success and eventually shipped over 10 million copies in the U.S., Green Day is credited alongside fellow California punk bands including Sublime, Bad Religion, The Offspring and Rancid with popularizing mainstream interest in punk rock in the United States.
Though Insomniac (1995), Nimrod (1997) and Warning (2000), did not match the success of Dookie, Insomniac and Nimrod reached double platinum and Warning achieved gold status. Green Day's seventh album, American Idiot (2004), a rock opera, found popularity with a younger generation, selling six million copies in the U.S. 21st Century Breakdown was released in 2009 and achieved the band's best chart performance. It was followed by a trilogy of albums, ¡Uno!, ¡Dos! and ¡Tré!, released in September, November and December 2012 respectively. Green Day's twelfth studio album, Revolution Radio, was released on October 7, 2016 and became their third to debut at number one on the Billboard 200.
