Big Boi calls on fellow Atlanta rap legends Ludacris and T.I. for this rowdy banger celebrating their hometown. "[With] 'In The A,' I just wanted to make a new A-Town anthem," he explained on MTV's RapFix Live. "Me and Tip been jammin' for some time now, we did 'Tangerine' on the last album, so it was time to get back in there and do it again. We went in the studio, and it was just mass murder. I'm all about MCing and those are two of my favorite MCs, so I said let's get on here like the three horsemen and let's kill it. Me and T.I. and Luda got to jammin' - Atlanta ya'll gonna be proud. I'm talking about Magic City, get your ones together."
