By the time the group released Kerplunk - an album that is enriched by the addition of Tre Cool on drums, as replacement for the college-bound Al Sobrante - this was a group that had found its groove in a most commanding manner. Despite having once again recorded their music at basement rates, Green Day's second full-length release contains a number of classics, of which 2,000 Light Years Away and Christie Road are merely two. Kerplunk even features the original version of Welcome To Paradise, a song the group would reprise on Dookie to devastating effect. And while it would still be two years before the world at large would know this group's name, by the time the tour in support of Green Day's second album had reached its conclusion its creators were drawing up to 2,000 people a night to see them play. In 1994 it may have looked as if their success had arrived overnight, but really it was anything but.
