Kerplunk (album)

Kerplunk (stylized as Kerplunk!) is the second studio album by the American rock band Green Day, released on December 17, 1991, by Lookout! Records. It is the band's first album to feature drummer Tré Cool, replacing original drummer John Kiffmeyer, who left the band to attend college following a US tour promoting their debut studio album 39/Smooth (1990). By this stage, Green Day's audience expanded to teenage girls from suburban towns.
