Last week Chief Keef announced that he would be leaving Interscope Records. This week, Gucci Mane announced that he and Chief Keef will be teaming up for a joint mixtape titled Big Gucci Sosa. Today Gucci Mane released the cover art for the upcoming mixtape via his Instagram page with the caption "#Big Gucci Sosa....Otw." The cover art depicts the two rappers as everyone's favorite Halloween characters Jason Voorhees and Freddy Krueger. No release date has been confirmed. This should be interesting.
