According to Miss Info:
“Everything “In the A” isn’t so sweet. Big Boi stomps through the streets of Atlanta with T.I. and Ludacris in his new visual to bring in 2013. The Outkast member welcomes you to the westside for the bass-knocker off his (album) out now.
The “isn’t so sweet” reference is probably due to the fact that the trio eschewed the nouveau riche, glossier, flossier parts of Atlanta and chose instead to romp through grittier parts of the city like Adair Park, Mechanicsville, Pittsburgh and other areas surrounding, the culturally-rich, but sometimes seemier West End.
