If you want this year's Lollapalooza lineup a little early, it's all yours—but you have to earn it. Taking their inspiration from Wheel of Fortune (of all places), the Lolla folks are giving you one letter each day, as well as the opportunity to guess this year's headliners before they are officially announced.

As of today, you have the letters I, R, and O to work with.

Lollapalooza is happening in Chicago, August 6-8. Advance three-day passes are currently available, so stop squinting and check out a larger version of the lineup puzzle at lollapalooza.com.
