Even behind bars, Lil Wayne stays on his grind. Weezy drops a freestyle over Drake’s Jay-Z assisted track “Light Up” from Thank Me Later. The verse was recorded during one of Wayne’s phone calls from prison and premiered during Drake’s Ustream session on Tuesday night. Drizzy calls it “one of the most incredible Lil Wayne verses [he’s] ever heard.”

Drake also revealed that he and Wayne are planning a joint album. “I went up to Rikers, and me and Wayne agreed that there will be a Lil Wayne/Drake album,” he told DJ Envy. “[This project] will probably be one of the most exciting things in my life, because we make music on a different level.”
