Music fans who attended this year’s Lollapalooza, which took place this past weekend in Chicago, were given an iTunes card that can be used to download a special collection of free tracks from artists who performed at the large festival. Lollapalooza organizers also said that live recordings from select bands on the festival’s top four stages will be available exclusively on the iTunes Music Store for 30 days. The live tracks have yet to be posted, however, and no release date has been given. In another partnership with iTunes, Lollapalooza attendees can also send a cell phone text message to receive setlists from the festival. After texting the keyword “setlist” and your email address to 56658, you’ll receive an email that will link directly to the setlists on iTunes.
