Kirko Bangz is riding a wave of hype following the release of his Progression III mixtape so it is only right that he team up with R&B crooner of the moment August Alsina for the remix to "Rain Down."

Alsina, coming off a huge win with his "I Luv This S***" single hitting #1 on the Billboard Mainstream R&B chart, provides his vocal talents to this song which should set the mood during this clutch time of Cuffing Season. Progression III is available for download now.
