Mos Def performs new music that features tracks by Madlib and J. Dilla (Video)

The Mighty Mos Def (soon to be Yasiin Bey…though he’ll always be Mighty) performed some new songs at New York’s S.O.B.’s. The tracks were produced by Madlib and J. Dilla (click here for a new song from Immortal Technique that also sports a previously unreleased Dilla beat). In a word–RUGGED. Check out the video of the performances below.
