Yasiin Bey (former Mos Def) and Talib Kweli together form Black Star as you may know. The duo only released one album (in 98′) which I consider one of my favorite hiphop albums ever. Anyhow, now they are apparently back in the studio together as Black Star and they performed the new track “Fix up” (prod. Madlib) on Colbert show. The shit is going to be HOT!
