Two of ATL’s biggest rap artists, B.O.B. and Big Boi, have teamed up to craft a brand new track called ‘Double Or Nothing’. This will serve as the official theme song for ‘Army of TWO: The Devil’s Cartel’ video game. The demo for the game is out now and if you pre-order it, you will be able to play as B.O.B. and Big Boi.
