J Cole definitely one of my favorite Emcees of his era, watching his growth as a lyricist and a man was amazing. I remember he was in Dave Chappelle "Block Party" not as a performer but in the audience.
Later I learn Talib Kweli & Mos Def were two of his mentos before J Cole was a household name.
His music will last the test of time, being that he writes his own lyrics, make his own beats, and produce other artists. He will get "The Bag" one way or another, what is live performance below and tell us what you think.
