Rapper Talib Kweli of Black Star and DJ Hi-Tek will release an album together called Train of Thought in May, according to Rawkus Records. The two first collaborated last year on the song "On Mission" from the compilation Rawkus Presents Soundbombing II. The new album's first single, "The Express," uses a jazz- and symphonic-inspired beat. With partner Mos Def, Kweli released Mos Def and Talib Kweli Are Black Star in 1998. That album won praise for its blend of nationalist politics and old-school hip-hop.
