Produced by: Metro Boomin Support: iTunes

To begin the promo run for their newly released Double or Nothing collab project, Big Sean and Metro Boomin took to Jimmy Fallon's late night stage to perform a medley of their cuts titled 'Who's Stopping Me' and 'Savage Time'. Metro can be seen behind the boards as Sean maneuvers the stage, flawlessly executing his performance. You can watch that above, and listen to their new album on iTunes if you haven't already.
