This was at his gig last night at North Atlantic Trade Center in ATL, GA. I was there and it was a great set for the most part even if there was a bit of monotony towards the middle. I did not take this video but this was taken by my friend as the last song (Lethal Industry) plays out.
As usual Tiesto left before anyone could even think about an encore but this seemed a little bit out of character, even for Tiesto. I noticed through the night that he wasn't really into it and looked like something was bothering him. Some people said it was because they told him to end his set early but I seriously doubt that was the case.
On a side note the crowds were huge! The line stretched from the door to the entrance of the plaza and many people didn't even get in.
