Green Day is an American rock band formed in 1987. The band consists of three core members:
Billie Joe Armstrong (guitar, lead vocals), Mike Dirnt (bass) and Tre Cool (drums).
Green Day was originally part of the punk rock scene at 924 Gilman Street in Berkeley, California.
Its early releases for independent label Lookout! Records earned them a grassroots fanbase,
some of whom felt alienated when the band signed to a major label.
Nevertheless, its major label debut Dookie became a breakout success in 1994 and eventually sold over
10 million copies in the U.S. alone. As a result, Green Day was widely credited, along with fellow
California punk bands The Offspring and Rancid, with reviving mainstream interest in
and popularizing punk rock in the United States. Green Day's three follow-up albums,
Insomniac, Nimrod and Warning did not achieve the massive success of Dookie, but they were still
successful, reaching double platinum, double platinum and gold status respectively.
Its 2004 rock opera American Idiot reignited the band's popularity with a younger generation,
selling 5 million copies in the U.S.
