On this date twenty years ago, Green Day released their first full length album, 1039 Smoothed Out Slappy Hours, on Lookout! Records.

Originally this album was released in 1990 as 39 Smooth, but then it was released again in 1991 as a compilation album to include the band's first 3 EP's: 39 Smooth, Slappy, and 1000 Hours, which were recorded at the Art of Ears Studio in San Francisco, CA between 1988 - 1990. This is the only Green Day album that Tre Cool did not play on since John Kiffmeyer had not yet left the band.

In 2007, Green Day re-released this album on Reprise Records, calling it a "re-mastered" version. As of 2010, it has sold over 600,000 copies.

Take an hour out of your day and take a listen to this classic album. If you are a newer fan and haven't bought 1039 Smoothed Out Slappy Hours yet this would be the perfect time to buy it on iTunes or Amazon.
