With the 2012 Lollapalooza not underway until Aug. 3, the festival's 2013 dates have been announced. What you see above is an advertisement for the Chicago fest...that's been somewhat prematurely posted through the Chicago Transit Authority. According to the ad, the 2013 Lollapalooza will take place Aug. 2-4.
Of course, no performers have been revealed yet, but at this rate it isn't hard to imagine getting that information by the end of the week. [Idolator]
