Green Day is an American rock trio formed in 1987


The band has consisted of Billie Joe Armstrong (vocals, guitar), Mike Dirnt (bass guitar, vocals), and Tré Cool (drums, percussion) for the majority of its existence.
Green Day was originally part of the punk rock scene at 924 Gilman Street in Berkeley, California. Its early releases for independent record 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 (1994) became a breakout success and eventually sold over 10 million copies in the U.S. and 15 million worldwide.As a result, Green Day was widely credited, alongside fellow California punk bands The Offspring and Rancid, with reviving mainstream interest in and popularizing punk rock in the United States. Green Day has sold over 22 million records in the United States.[8] They have won three Grammy Awards, Best Alternative Album for Dookie, Best Rock Album for American Idiot, and Record of the Year for ,Boulevard of Broken Dreams.
