Can anybody disagree with the fact that Jane's Addiction with the original lineup is a lock to headline one of the nights this year? They are currently playing tiny clubs in LA warming up for a tour and Perry is always there. I personally can't wait to see Three Days and Ted Just Admit It played in front of 50,000 strong in the desert!! It's gonna be amazing!! I'm sure all of you Perry hters will jump all over this thread but you are all in denial if you think they won't be there and don't carry headliner status.
As for the other two nights, I'll put my money on Pearl Jam and Bowie.
