Ohhhh yeah, last night Jimmy Fallon set the bar high for the rest of the year with a visit from Black Star aka the pairing of Mos Def and Talib Kweli. Performing alongside The Roots they put in performances of two tracks from their Aretha Franklin inspired mixtape. For the masses watching at home they performed "You Already Knew" whilst J-Fal also upped a web exclusive performance of "Little Brother". Give the Former a look at the top whilst the web exclusive performance is viewable after the jump. Many thanks to the ever trusty Audio Perv for the video support.
