I really don't know if it is, but it adds up. A lot of those bands are 'to be confirmed': like all the headliners, The Black Keys and stuff. It's also looks as if it is part of a magazine, suggesting that it could be an early print.
See, the Lollapalooza board I'm on occasionally is full of seasoned people that have been there for years and years and all they do is act like complete assholes towards EVERYONE, even each other. It's an entirely different atmosphere, and I HATED it at first and instead would just always stay here...but then I realized they're all just messing with each other and have extremely thick skin. They know how to take a joke. And they're really funny.
So if I act like more of a dick towards anybody in the near future I probably just came from there.
Except for around johnthedude. He practically invites it.
