Green Day

Green Day is an American rock band formed in the East Bay of California in 1987 by Billie Joe Armstrong and Mike Dirnt. The band was initially called Blood Rage, then Sweet Children, and they were part of the late 1980s/early 1990s Bay Area punk scene that emerged from the 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. Alongside fellow California punk bands such as Bad Religion, The Offspring, Rancid, NOFX, Pennywise, and Social Distortion, Green Day is credited with popularizing mainstream interest in punk rock in the U.S.
