It's been three years since Dr. Dre's third solo disc was supposed to hit shelves. But Dre's publicist says, "Dre's currently working on Detox, which is planned for release this year. It's the third part of the trilogy, which began with The Chronic and will be Dre's final album." Jay-Z recently talked about working on the CD, and appearances by 50 Cent and Eminem seem likely.
