Fun story: my friend used to work for the company that does security/ticket-taking/whatever at these events. She worked Rockfest a few years ago and was in charge of checking passes for people to go to the "backstage" area and she said she saw Corey Taylor throw the hugest whiniest shit-fit because he had just performed his first ever solo show and no one liked it.
