The short-lived California punk band the Lookouts didn't make much of a dent in their day, but they turned out to be the launching pad for Tre Cool of Green Day and Larry Livermore of Lookout Records. In 1987 they released their debut album, with Livermore founding the Lookout Records label to release the record. For their fourth record, Livermore brought along his friend Billie Joe Armstrong to play additional guitar on the sessions, and when Billie's new band was in need of a drummer, Tre agreed to sit in with them for a while. Billie's band was, of course, Green Day, and while the Lookouts didn't officially break up, Green Day soon became successful enough that Tre stayed with them full-time. ~ Mark Deming
