"Kerplunk" was Green Day's last release on the Lookout Records label, and was also the first album to feature Tré Cool on drums.  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 Book Mobile and headed east.  Green Day developed a fan base on the east coast, behind the determined grass root 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 "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".
