Like to be honest, the Oak Park dudes really dont owe anything to Bo and them. Their sound is in no way of that lineage, they didnt help put em on, the hoods have beefed since before Tim was born.
Now some younger GB rapper or just anyone in general running that dark mob influenced sound, or that sicc shit that makes that statement, then ya they are trippin.
Atl had that southern funk sound that Outkast was doing and the dope boys (jeezy, t.i, scrappy)did something completely new with that trap sound. Thats how I equate it.
