Earlier this year, Houston rapper and singer Kirko Bangz dropped Progression III, the latest in his series of mixtapes charting his rise in the rap game, and one of the select cuts from the tape was "Rain Down," a moody ballad produced by Sound Mob. Now, Bangz is back with an even smoother remix of the track featuring August Alsina, the Def Jam-signed crooner behind the radio-dominating "I Luv This Shit." It's a potent combination. Check out the remix above.
