CHICAGO (CBS) –  Blackbox frontman Damon Ranger of CBS 2 takes you backstage and behind the scenes to show you the VIP lifestyle, celebrity swag and secret shows at the 20th anniversary of Lollapalooza.

Lots of exciting events happened over the three-day fest at Grant Park, including a celebrity kickball game pitting L.A. celebs against Chicago musicians.

Up until six years ago, Lollapalooza was a traveling touring festival. Now it makes its yearly residence in Chicago, but starting in 2012 it will also be in Sao Paulo, Brazil.

 ”Twenty years ago, I expected to see 10 to 20,000 weirdos,” Lollapalooza founder Perry Farrell said. “Now I am proud to say we have 90,000 weirdos showing up in the city of Chicago.” 

Featuring the Foo Fighters, Elijah Wood, Perry Farrell, Questlove, John Legend, Deftones, Mick Jones, Ok Go, Samantha Ronson, Taylor Momsen, Skylar Grey, Tinie Tempah, Chris Holmes, and many, many more.
