They been gone for nearly 10 years, what did they expect??
They should have never been thrown on a festival as the headlining acts right out the gate. Outkast might have been stars but they weren't the fucking Beatles, they were never big enough to warrant a Headlining gig for a crowd of 30,000 people after an 8 year Hiatus (Really longer then that if you take into consideration the fact that "Idlewild" kinda flopped)
Looks like a good set but they set themselves up for disaster, they should be working on rebuilding the momentum because it hasn't lasted through the years, if Outkast put out a new album tomorrow it would have a hard time going gold just off of nostalgia. Alot of the white crossover fans they once had have forgotten about them. Sad but true.
