Kerplunk is the second studio album by the American punk rock band Green Day. It was released on January 17, 1992 through Lookout Records. Kerplunk was their last release on Lookout Records and was also the first album to feature Tré Cool on drums. The album has gone on to be among the best selling independently released albums of all time. After debuting the album to their fans in the Berkeley, California area and receiving much approval from the critical 924 Gilman Street crowd, the band packed up in a cramped, converted Book Mobile and headed east. The band developed a fan base on the east coast behind the touring support of grassroots promotor, Jak Werz. The risk paid off as album sales reached over 50,000 copies. Along with the albums sales and the successful live shows, major labels took notice of Kerplunk's phenomenal popularity, as a result, many approached the band. Green Day realized that they had outgrown their record distribution capacity with Lookout! and eventually signed with Reprise Records. With Reprise, Green Day recorded and released their next album Dookie (1994).
