39/Smooth

39/Smooth is the debut studio album by the American rock band Green Day, released on April 13, 1990, by Lookout Records. After finalizing their line-up, the band played frequent shows at the 924 Gilman Street venue, where they started attracting a following and eventually caught the attention of Lookout Records' founder Larry Livermore. Following the release of their debut EP 1,000 Hours (1989) and stints in other bands, Green Day went to Art of Ears Studio, located in San Francisco, California, to record their debut studio album, which was co-produced with Andy Ernst. Sessions started at late December 1989 and ended in January 1990, costing $675.
