The only big rappers to come outta there the last 20 years are David Banner, Big Krit & Soulja Boy. David was straight early on doing his underground Southern rap with the Firewater Boyz, then he did ringtone music and his career went down the drain. Everyone knows Krit is nice. Soulja Boy is, well, Soulja Boy & he always claimed ATL, except when he first came out he was admitting he moved to Mississippi with his dad.
Mississippi has such a storied musical history with blues & soul music, you'd think there'd be way more influential rappers.
