Dodging retirement rumors, Eminem will spring back into action this winter with "Eminem Presents: The Re-Up," a mixtape disc that will serve as an introduction to new artists from his Shady Records camp. Eminem produced the majority of the tracks, with assistance from the Alchemist, and also raps on a handful of cuts.

Due Dec. 5 via Shady/Interscope, "The Re-Up" was intended as a purely street-level project with rough-hewn production, but quickly blossomed into something greater. "Instead of putting it out there rough and unfinished, I thought we should add some other new tracks, make it a real album and put it in the record stores to give these new artists a real boost," Eminem says.

On "The Re-Up," the spotlight is on Atlanta up-and-comers Stat Quo and Bobby Creekwater as well as ex-Renegadez member Ca$his. The first single and video is "You Don't Know," which features Eminem, 50 Cent, Lloyd Banks and Ca$his. Eminem also takes the mic on "No Apologies," while D12's Bizarre and Kuniva appear on "Murder."

Eminem quashes speculation that "The Re-Up" would serve as a tribute to his recently slain close friend, Proof, saying the upcoming project "is about these new artists and these new songs. It isn't fair to them or to the memory of Proof to mix them up."
