We haven’t heard much new material from Roc Nation’s J. Cole since his debut, Cole World: The Sideline Story, was released last September. But we might just have heard a preview from his upcoming sophomore album. During his performance at the 2012 Wireless Festival in London, he rapped some new bars for his UK fans before going into “Nobody’s Perfect.” The verse made some references to Nas, Jay-Z, and the Notorious B.I.G and sounded like Cole hasn’t lost his touch.
