Lollapalooza is an annual American music festival held over four days in Grant Park, Chicago. It originally began in 1991 as a touring festival created by Perry Farrell, the lead singer of Jane's Addiction, initially intended as the band's farewell tour. The festival features a wide variety of music genres including alternative rock, heavy metal, punk rock, hip hop, and electronic dance music. Since 2005, Lollapalooza has been held as a destination festival at Grant Park, growing from a two-day event to the current four-day format by 2016. It is one of the largest and longest-running music festivals in the United States, attracting around 400,000 people each year. Besides music, Lollapalooza incorporates visual arts, nonprofit organizations, and political awareness activities. The festival includes multiple stages with headlining acts, side stages for up-and-coming artists, and a dance tent for electronic music. There is also a family-friendly area called Kidzapalooza, catering to younger fans with musical performances and workshops. The festival has expanded internationally with editions in several countries past its Chicago origins.
