Kerplunk (stylized as Kerplunk!) is the second studio album by the American rock band Green Day, released on December 17, 1991, by Lookout! Records. Following a US tour promoting their debut studio album 39/Smooth (1990), drummer John Kiffmeyer left to attend college and was replaced by Tré Cool, formerly of the Lookouts. By this stage, Green Day's audience expanded to teenage girls from suburban towns. In May 1991, they decamped to Art of Ears Studios in San Francisco, California, to record their next album with Andy Ernst, who co-produced the sessions with band. Six songs were recorded until the proceedings stopped in order for Green Day to resume touring, returning to the studio in September 1991 to finish the work.
