Rae Sremmurd made their debut on The Tonight Show Starring Jimmy Fallon to perform the hit singles "No Type and "No Flex Zone." The duo hit the stage backed by The Roots to perform the singles, in their unique style of dress and similarly unique dance moves, and didn't miss a beat during the medley of the two songs. This has been an incredible year for the duo, as they debuted from relative obscurity earlier this year under the tutelage of their producer Mike WiLL Made It. Watch the video above. Rae Sremmurd's debut album SremmLife drops on January 6.
