Warning (Green Day album)

Warning (stylized as Warning:) is the sixth studio album by the American punk rock band Green Day, released on October 3, 2000, by Reprise Records. Building upon its predecessor, Nimrod (1997), the album eschewed the band's trademark punk rock sound and incorporated acoustic elements and pop and folk styles. Lyrically, the record contains more optimistic and inspirational themes in comparison with the band's earlier releases. Warning was also Green Day's first album since Kerplunk (1992) that was not produced by Rob Cavallo, although he did have a hand in its production and was credited as executive producer.
