39/Smooth is the debut studio album by American rock band Green Day, released on April 13, 1990, by Lookout Records. It was the band's only album to feature second drummer John Kiffmeyer. Jesse Michaels of Operation Ivy contributed the artwork on the album. The inner sleeve shows handwritten lyrics by Billie Joe Armstrong and letters by drummer John Kiffmeyer and Lookout owner Larry Livermore to I.R.S. Records, rejecting a fake offer to sign to the label and declaring its loyalty to Lookout (however, the band would later leave the label and move to Reprise Records). There were no official singles released from the album, although "Going to Pasalacqua" was released as a mock-up single in a Green Day singles box set entitled Green Day: Ultimate Collectors.
