So far every rapper from the beginnings in the 80s to today that have blown up have all been from a major city or some kind of surrounding urban hood near it. So far every rapper that is from an average middle class suburb has never made it so far in their rap careers. Even those rappers who are from suburbs that had made it so far had to claim they are from some nearby city or known hood to get recognition(examples are Ice Cube and Dr. Dre). There isn't much in place for a rapper from a regular small town suburb to make it to be honest.
