With Underground Luxury creeping upon us, B.o.B releases “Throwback,” a new track featuring Chris Brown. In a song that will find its way to a nightlife venue near you, you get some new bars from Bobby Ray but also the hip hop version of Chris as well. Underground Luxury is set to release on December 17 and is currently available for pre-order on iTunes.

Check out the new track from B.o.B and Breezy after the jump.
