Released in 1991 by Lookout! Records, this compiles Green Day's first LP 39/Smooth with their first two EPs, 1,000 Hours and Slappy. This collection stands as a triumph of the underground East Bay pop-punk scene before the major labels swooped in. Sure, it's raw and ridged in parts, but what the band lacks in proficiency, they make up for in unadulterated fun. "At the Library" starts things off with a bang that peaks on tracks like "Green Day," "Going to Pasalacqua" and the quirky cover of Operation Ivy's "Knowledge."
