What did Green Day win a Grammy for in 2005?

Green Day won a Grammy for Best Rock Album in 2005. The winning album was American Idiot, the band’s ambitious seventh studio album and a landmark punk-rock opera.

Released on September 21, 2004, American Idiot was built around a loosely connected story about disillusionment, media influence, war, and rebellious youth. Its political title track and theatrical structure marked a major change from Green Day’s earlier, more straightforward pop-punk records.

At the 47th Grammy Awards in February 2005, the album won Best Rock Album. Green Day also performed “American Idiot” during the ceremony. The record was nominated in several other categories, including Album of the Year, but did not win that award.

Another common mix-up concerns the band’s later Grammy success. “Boulevard of Broken Dreams,” also from American Idiot, won Record of the Year in 2006, while the album itself earned the Best Rock Album award in 2005.
