Mos Def

Like many rappers, New York underground hip-hop hero Mos Def was first heard on guest appearances with other artists, in this case Da Bush Babees and De La Soul. It was his 1998 collaboration with the like-minded Talib Kweli in the duo Black Star that brought him fame, however. A subsequent solo album full of similarly progressive tracks was well received, but it was Mos Def's film roles in the late '90s/early '00s (THE ITALIAN JOB, BAMBOOZLED, BROWN SUGAR, etc.) that heightened the forward-looking rapper's profile even further.
