Originally released in February 1999, The Slim Shady LP, the rapper's second artist album and his major-label debut, is considered Eminem's breakthrough project, elevating him from underground rapper to breakout pop star. The album, which debuted at No. 2 on the Billboard 200 chart, has since gone four-times-platinum in the U.S. The Slim Shady LP went on to win the GRAMMY for Best Rap Album and Best Rap Solo Performance, for album track "My Name Is," at the 42nd GRAMMY Awards, held in 2000.

Pre-orders for The Slim Shady LP [Expanded Editions] from Eminem on vinyl and CD are available now.
