Eminem
Eminem made his first appearance in a year in September 2008 at his radio station, the Shade 45, where he said: "I'm concentrating on my own stuff right now—just bangin' out tracks. The more I keep producing, the better it seems I get. I start knowing stuff, learning the boards like the back of my hands." In an interview with Billboard in December 2008, he revealed that the album would be released in the spring on 2009, be called Relapse, and most of the tracks would be produced by Dr. Dre.
