Killer Mike has been making moves lately and one of those moves has been an appearance on, ‘The Late Show with David Letterman‘ to perform his single, “Untitled.” The Atlanta native will be busy for the next few months to come since he has the ‘Shoes for Running’ tour with Big Boi coming up April 18th, and not one, not two, but three more albums to be released.
