If you don't have tickets to Lollapalooza yet, you have missed out on the three-day passes, they're sold out already. So, the other two options are single-day tickets or VIP tix.

The full lineup won't be announced until April 9, so if you get your tickets now you'll just have to hope it is worth the money. Sounds like some kind of Obama thing don't it? The Chicago Tribune has found out who some of the acts are, Mumford & Sons, Phoenix, the Killers, the Postal Service and the National.

Lollapalooza will be Aug. 2-4 in Chicago's Grant Park. Check here for prices on VIP/Platinum passes.
