After stating in an interview recently that “”I just get more fulfillment out of singing now. I’m teaching myself the guitar, that’s like my newfound love,” last night Kid Cudi took to the stage on Letterman with guitar in hand to play the lead single “Erase Me” off Man on the Moon II: The Legend of Mr. Rager, due out November 9. The single features Kanye West, but Mr. West is in London working on his upcoming Jay-Z collbo album so he was obviously unable to make the performance. However, another very special guest showed up to help tear up the strings, rock legend Slash, who was revealed at the end of the song but who had been playing along the whole time. The performance was solid with Cudi giving it his all. Watch the full video below.
