Arguably one of the best duos in rap, Mos Def and Talib Kweli have a style and sway that comes from a strong background in NYC. Their sound is unique and they are very talented rhymers. After releasing Black Star in 1998 they broke up, yet many of their songs are collabortions with the other and it does a good service to the music. All of these songs are great and interesting to listen to. Check them out.
