Last night, Mos Def and Talib Kweli revived Black Star for a pair of performances on Late Night With Jimmy Fallon, first performing a new song, "You Already Knew," before hitting the J Dilla-produced "Little Brother" from The Hurricane soundtrack. With the legendary Roots crew in step, it's just as smooth as you're imagining it to be. Check out the videos after the jump.

Aretha Black Star, a new free mixtape from the group, is out soon. In October, Black Star took to Colbert to play a new jam called "Fix Up," the old jam "Astronomy (8th Light)" as well as doing the sit-down interview thing.
