There is a long, long list of artists that have been in the studio with Dr. Dre over the years, and even though he recently said that he's planning on taking a break from music soon, he's still been hard at work and putting in studio time with plenty of artists. Last time we saw him in the lab, he was accompanied by Rick Ross and DJ Khaled. And now, according to his protégé Slim The Mobster, Dr. Dre has been working on Detox with Lil Wayne.
