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).
The album officially includes only 12 tracks, but the versions released on CD and cassette also include the 4 tracks from the Sweet Children EP. One of those tracks is a cover of The Who's "My Generation". The song "Welcome to Paradise" was re-recorded for Dookie.
Like Dookie, Kerplunk was banned from certain stores because of the cover art. The cover features a mostly white picture (with some green added in) of a high school girl with a gun that has been fired. On the back cover, there is a boy lying on the ground with a gunshot wound on his back.
In August 2005, Green Day pulled the album, as well as all of their other material released through the label, from Lookout! due to unpaid royalties.[http://www.punknews.org/article/13338 Punknews.org | Lookout! downsizes, scales back plans for the future] It was reissued on CD by Reprise Records, who Green Day has been with since leaving Lookout!, on January 9, 2007.[http://www.amazon.com/dp/B000JMKKG8 Amazon.com: Kerplunk: Music: Green Day] In Europe, the album was released by Epitaph Europe, and has remained in print. It was reissued on vinyl on March 24, 2009 by Reprise Records and includes a reissue of the Sweet Children EP.
There were no official singles released from the album. Although, "2000 Light Years Away" and "Christie Road" were released as mock-up singles in a Green Day singles box set entitled Green Day: Ultimate Collectors.
