Rappers evolve, as do producers. A lot of people over the years have asked "why doesn't ___ go back to using ____ with that mobb shit!!?" Why? Because the era was that era, and more than likely, the producer just has a different sound now. Is that always the case? Of course not, as we saw what TC can still do. However, Mosely, Bostic, K-Lou, etc...they are different beat makers now.
All im sayin is, people expecting Illegal Business? part 2 circa 1995....maybe you should lower your expectations just a tad, becuase the chances of that happening are slim.
