Kerplunk!

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 an independent label and was also the first album to feature their current band lineup, with Tré Cool on drums. The album has gone on to be among the best selling independently released albums of all time. Major labels took notice of Kerplunk's phenomenal popularity and 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 would record and release their third, and most successful 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 4 tracks is a cover of The Who's "My Generation". One of the tracks, called "Welcome to Paradise", was re-recorded on the 1994 album Dookie .
Because the band did not use guitar tuners when recording Kerplunk and simply tuned "by ear", the songs are not in standard tuning. They are actually tuned just below Eb, making it difficult for guitarists and bass players to play along unless they tune specifically to the album. This tuning style gives the guitars on Kerplunk a somewhat darker and unique sound.
As of August 2010, Kerplunk had sold 753,000 units in the United States and 1,000,000 units worldwide.
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. 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 and includes a reissue of the Sweet Children EP.
In December 2007, Blender magazine ranked Kerplunk number 47 on their list, "The 100 Greatest Indie Rock Albums Ever".
