Kerplunk (stylized as Kerplunk!) is the second studio album by American rock band Green Day, released on December 17, 1991, by Lookout! Records. Kerplunk was Green Day's last independent release on the Lookout Records label, and was also the first album to feature Tré Cool on drums. Kerplunk 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". Green Day guitarist and singer Billie Joe Armstrong stated in a 2021 Vulture magazine interview that Kerplunk is his favorite album, citing it as "kind of autobiographical." Music Kerplunk's sound has been described as punk rock, pop punk, and indie rock. Artwork 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 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. Release The album sold 10,000 copies its first day and became Lookout!'s biggest-selling release. After debuting it 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 Bookmobile and headed east. Green Day developed a fan base on the east coast by way of the determined grassroots efforts of lead singer Billie Joe Armstrong. The opportunity paid off, as album sales reached over 50,000 copies. Along with the successful live shows, major labels took notice of Kerplunks phenomenal popularity. As a result, many labels 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). In August 2005, Green Day pulled the album – as well as all of their other material released through the Lookout! label – due to unpaid royalties. It was reissued on CD by Reprise Records, who Green Day has been with since leaving Lookout!, on January 9, 2007. 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. There were no official singles released from the album, although "2000 Light Years Away"
