When the last Progression mix came out, Kirko Bangz was nowhere near as well known as he is now. Perhaps that's the beauty of the Progression series; there's some real, erm, progress being made. Not just career-wise but musically as well.
Experience Progression 3, the latest tape from Kirko Bangz. It dropped on Monday, August 12th, 2013. Kirko Bangz's odds keep getting better with each new leak, and Progression 3 will undoubtedly improve his chances of winning.
