Lollapalooza also sold out in both 2008 and 2009, reaching a total fest capacity of 75,000 concert-goers per day, which means that in those years over 225,000 fans came to Chicago's Grant Park to see acts like Radiohead, Nine Inch Nails, Kanye West and Kings of Leon. In 2007, the number of people in attendance was roughly about 160,000.
The Lollapalooza 2011 lineup includes Eminem, Foo Fighters, Deadmau5, Cee Lo Green, and Coldplay in addition to over 100 other acts. Jane's Addiction singer, Perry Farrell founded Lollapalooza as a traveling music festival in 1991. Between the years of 1991-1997, Lollapalooza traveled throughout the United States before disappearing until 2003. C3 Presents event promotion company, along with publicity from Fresh Clean Media, took over in 2005 and re-conceived it as a three-day music extravaganza centered in Chicago's Grant Park, adding an acclaimed food area, a special stage for kids, and a farmers market.
In January 2008, C3 Presents signed a ten-year contract extension with the Chicago Park District and Parkways Foundations to keep the music festival in Chicago.
