Green Day is a Californian punk rock band formed in the late 1980s by Billie Joe Armstrong, Mike Dirnt and Tré Cool. Emerging from Berkeley’s underground scene, the trio exploded in 1994 with Dookie — a punk masterpiece that reached the mainstream while staying true to its DIY roots.

Green Day’s music blends catchy melodies, raw energy and lyrics that swing between irony, rebellion and youthful angst. Albums such as Insomniac (1995), Nimrod (1997) and Warning (2000) show their stylistic growth, while American Idiot (2004) and 21st Century Breakdown (2009) cemented their status as politically charged punk icons.

With millions of albums sold and a lasting influence on modern punk, Green Day stands alongside Blink-182 and The Offspring as one of the defining bands of the genre.
