Green Day

Green Day is an American rock band formed in Rodeo, California, in 1987 by lead singer and guitarist Billie Joe Armstrong and bassist and backing vocalist Mike Dirnt, with drummer Tré Cool joining in 1990. In 1994, their major-label debut Dookie, released through Reprise Records, became a breakout success and eventually shipped over 20 million copies in the US. Green Day has been credited with reigniting mainstream interest in punk rock.

Before taking its current name in 1989, the band was named Sweet Children. They were part of the late 1980s and early 1990s Bay Area punk scene that emerged from 924 Gilman Street, a club in Berkeley, California. The band's early releases were with the independent record label Lookout! Records, including their first album 39/Smooth (1990). For most of the band's career, they have been a power trio with Cool, who replaced John Kiffmeyer in 1990, before the recording of the band's second studio album Kerplunk (1991). Though the albums Insomniac (1995), Nimrod (1997), and Warning (2000) did not match the success of Dookie, they were still successful, with Insomniac and Nimrod reaching double platinum status, while Warning achieved gold. Green Day's seventh album, a rock opera called American Idiot (2004), found popularity with a younger generation and sold six million copies in the US. Their next album 21st Century Breakdown was released in 2009. It was followed by a trilogy of albums, ¡Uno!, ¡Dos!, and ¡Tré!, released in September, November, and December 2012, respectively. The trilogy did not commercially perform as well as expected, in comparison to their previous albums, largely due to a lack of promotion and Armstrong entering rehab. These albums were followed by Revolution Radio (2016)—their third to debut at No. 1 on the Billboard 200—Father of All Motherfuckers (2020), and Saviors (2024).
