This is the original version of Mos Def's song "Brooklyn." The album version is found on his debut "Black on Both Sides." On the original version, Mos Def is rhyming over "Incarcerated Scarfaces" by Raekwon as well as "Give Up the Goods (Just Step)" by Mobb Deep, and "Who Shot Ya?" by The Late Great Notorious B.I.G. This is definitely a rare song.
