Green Day's debut EP, 1,000 Hours – which features drummer John Kiffmeyer (A.K.A. Al Sobrante) – was the band's first effort for Lookout! Records. But the four-song effort is also significant for being their first release as Green Day. The band made the switch from Sweet Children mere weeks before the EP's release in April 1989, reportedly due to the existence of the similarly-monikered East Bay act Sweet Baby – a move that, according to Lookout! head Larry Livermore, made him go "ballistic."
