Lollapalooza is the midwest's premiere music festival, if not the nation's. Held over four days and selling out every year, it brings one of the most diverse array of music acts to the Windy City for hundreds of thousands of fans to enjoy. Chicago's Grant Park is the perfect grounds for a festival this huge, and you won't want to miss out on one of the best long weekends imaginable. If you're looking to make it out to Lolla this year, be sure to find the cheapest Lollapalooza tickets on TickPick, where you'll NEVER pay any service fees!
