It's just been anounced that Joey Bada$$ with the Pro Era crew will be added to the line-up, along with A$AP Mob, The Internet, Action Bronson, Stalley, Trinidad James, Logic, and Young Dirty Bastard. These are the new additions to the roster amongst Wu-Tang Clan, Rakim, Slick Rick, Big Daddy Kane, Common, Black Hippy, J. Cole, Talib Kweli, Tyler the Creator, Earl Sweatshirt, Curren$y, Kid Cudi, Freddie Gibbs, Danny Brown, Sean Price, Big K.R.I.T, Flatbush Zombies, Bone Thugs N Harmony, and many more. It's going to be another great year of new and old school acts under one roof and you can get your tickets here.
