Lollapalooza /ˌlɒləpəˈluːzə/ is an annual music festival featuring popular alternative rock, heavy metal, punk rock and hip hop bands, dance and comedy performances, and craft booths. It has also provided a platform for non-profit and political groups.

Conceived and created in 1991 by Jane's Addiction singer Perry Farrell as a farewell tour for his band, Lollapalooza ran annually until 1997, and was revived in 2003. From its inception through 1997, and its revival in 2003, the festival toured North America. In 2004, the festival organizers decided to expand the dates to two days per city, but poor ticket sales forced the 2004 tour to be cancelled. In 2005, Farrell and the William Morris Agency partnered up with Austin, Texas-based company Capital Sports Entertainment (now C3 Presents) and retooled it into its current format as a weekend destination festival in Grant Park, Chicago, Illinois. In 2010 it was announced that Lollapalooza would debut overseas, with a branch of the festival staged in Chile's capital Santiago on April 2–3, 2011 where they partnered up with Santiago-based company Lotus. In 2011, the company Geo Events confirmed the Brazilian version of the event, which will be held at the Jockey Club in São Paulo on 7 and 8 April 2012.
