Before any of you up and move to Atlanta thinking that's going to be your golden ticket, do yourself a favor and go out there for a few weeks first. There is already a vast number of artists who are from Atlanta, and who moved there with the same idea in mind. Tons of studios, tons of people trying to make it, and tons of mistakenly high expectations. I know of a lot of "rappers" and "producers", some with a lot of talent, that wound up wasting a few years doing that.
In my opinion you're better off staying at home trying to get it crackin' on the internet or within your city limits unless you're already connected down there.
