Green Day's sophomore album found the band further tightening their sound. The lineup was now solidified with Tre Cool cementing his place on drums, Mike Dirnt on bass, and Billie Joe Armstrong delivering his trademark snotty voice and straightforward guitar riffs. "Kerplunk!" was the perfect test run for the trio's major label pop punk. Subsequent albums like "Dookie" would open doors for many of the bands that would follow in Green Day's wake. Dirnt and Cool's ultra tight rhythm section delivered guitar-less breaks that would go on to define the band's sound. The album is filled with catchy choruses and yearning lyrics. "Kerplunk!" offers plenty to like about the band and this special edition includes the "Sweet Children" EP on a separate 7".
