Lollapalooza's organizers sure are thinking ahead. While their 2012 iteration hasn't even kicked off yet -- the Chicago festival is set to take place over the weekend of August 3-5 -- ads in Chicago have gone up announcing that the fest will be returning August 2-4, 2013, a solid 373 days into the future.

Lollapalooza 2012 Lineup: Black Sabbath, Chili Peppers, Black Keys Headlining

Consequence of Sound reported the ads, which display a somewhat pre-emptive "Thank You Chicago!" slogan, a prominent "See you next year!" adieu to festival-goers who haven't even had a chance to show up yet this year, and a slew of sponsors, including Sony, Toyota, Citi, Bud Light, and more.

Lollapalooza was founded in 1991 as a touring festival by Jane's Addiction frontman Perry Farrell, before settling into its current one-weekend, Chicago-based format in 2005. C3 promotes the festival.

This year's event is still nine days away, and features headliners Black Sabbath, the Black Keys, and recent rock and roll hall of fame inductees the Red Hot Chili Peppers, as well as sets by Jack White, Florence and the Machine, Frank Ocean, and more in Chicago's Grant Park.

Lollapalooza started hosting a two-day festival in Chile in April 2011, while Lollapalooza Brasil was introduced to Sao Paulo in April, with the Foo Fighters and Jane's Addiction headlining. Eminem, Coldplay, the Foo Fighters and Muse served as headliners at last year's U.S. version.
