Good to hear Tiesto is good people. I agree that PVD is another DJ with a pretty good attitude. I did lasers/visuals for his show here last year. The promoter eventually decided to have a my friends leave the stage so PVD's management wouldn't bug, but before that, he was happy to greet a couple of them who sort of idolize him.
I do have to point out that the visuals he provided were LAME. I still have them. They're basically shots of him in Mexico or Italy and all kinds of album artwork -looped. At least he didn't give me a scratched DVD. (I was able to download the files before the event)
