Blackstar is hip hop duo Mos Def and Talib Kweli. They named themselves after the first black-owned ship liner to travel from the U.S. to Africa, the Black Star. The relevance of this naming is revealed in their music, which attempts to connect modern Black culture with both its African roots and its perversion in America.
The album "Blackstar" was widely acclaimed and was one of the top-selling albums of 1998. Interestingly, the album is now out-of-print, so copies are rare.
