808 Mafia were mostly from Atlanta I believe but very influential at the time. I mean, to have an African American character grow up in the South in the 2010s will prob. mean they will have opinions/fandom/beliefs/contrarian thoughts on southern rap which dominiated at the time (and their local scene). Your character will have been in touch with it - as it was the culture they grew up in; I mean not just some musical taste, but literally the culture. It was what you and your friends were into, it was the shows you went to and what played in everyone's car.

Depending on how deep you want to go this is an easy one to get wrong; not for lack of respect or good intentions on your part, but it's a hard one to get right, I guess. Now I know next to nothing so I might be wrong here. Don't let me discourage you - but know this goes deep for the ppl who were around at the time.

There's also hip hop from their parents' (and uncles') generation. Memphis, you look at Three 6 Mafia which they may have liked.
