Chief Keef is celebrating his 18th birthday with his new mixtape, Bang Part 2, scheduled to release tonight at 10:17 EST. With just a few hours before the drop time, Keef puts out a beautiful video for “Citgo,” which is directed by Wiliam Hoopes. The bonus track off Finally Rich turned into an instant fan favorite, and in the visuals we see Keef riding around ATVs and “smoking that gas” with his GBE crew.
