Turning songs into hits is all grist for Kevin “KD” Davis's mill. KD has been at the top of the mix game since 1995, when he hit the big time with his mix of Coolio's “Gangsta's Paradise.” Since then he's been churning out hits for Outkast, Trick Daddy, Usher, Mariah Carey, Pink, Trina & Kelly Rowland, Chris Brown, India Arie, Ne-Yo and many others, and is currently based at his own mix studio in Atlanta, Georgia.
