Mos Def & Talib Kweli Are Black Star is the only studio album by Black Star, a hip hop duo consisting of emcees Talib Kweli and Mos Def (the latter of whom now goes by the stage name Yasiin Bey). The album was released on September 29, 1998, to critical acclaim. The title is a reference to the Black Star Line, a shipping line founded by Pan-Africanist Marcus Garvey. The album deals with modern-day issues, philosophical ideas, and life in Brooklyn, New York City, as the two artists know it.
