When does Lolla: The Story of Lollapalooza return?

Lollapalooza was conceived and created in 1991 as a farewell tour by Perry Farrell, singer of Jane's Addiction. It originally started as a touring event in 1991, with Chicago becoming its permanent location in 2005. Music genres include alternative rock, heavy metal, punk rock, hip hop, and electronic dance music. The festival hosts an estimated 400,000 people each July and sells out annually. In 2010, it was announced that the festival would remain in Chicago, while debuting outside the United States in Chile.
