"It's free to get in, but we're charging you to get out," Ozzy joked at a press conference.
But seriously ... how does it work? According to the MTV story, "In order to get inside Ozzfest this summer, fans must visit the tour's Web site to find links that will direct them to special sponsor sites where tickets can be secured. More details regarding the process will be revealed in the coming weeks."
What remains to be seen is which bands will sign up for such a free concert and if fans are willing to jump through a plethora of online hoops to get those tickets.
