लोलापालूजा वार्षिक चार दिवसीय संगीत समारोह

Lollapalooza (Lolla) is an annual four-day music festival held in Grant Park in Chicago, Illinois. It started as a touring event in 1991. Music genres include but are not limited to alternative rock, heavy metal, punk rock, hip hop, and electronic music. Lollapalooza has also featured visual arts, nonprofit organizations, and political organizations. The festival in Chicago's Grant Park hosts an estimated 400,000 people each July and sells out annually. Lollapalooza is considered one of the largest and most iconic music festivals in the world and one of the longest-running in the United States.

Lollapalooza was conceived and created in 1991 as a farewell tour by Perry Farrell, singer of Jane's Addiction. The first Lollapalooza tour had a diverse collection of bands and was a commercial success. It stopped in more than twenty cities in North America. In 2020, Spin rated the first Lollapalooza as the best concert on a list of "The 35 Greatest Concerts of the Last 35 Years" Lollapalooza then 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 organizers decided to expand the dates to two days per city, but poor ticket sales forced the 2004 tour to be cancelled.
