The music festival has experienced its share of ups and downs since its inception by Perry Farrell in 1991. To see in its quarter-century, the festival is celebrating with a four-day lineup full of some of the music world's biggest names kicking off July 28. Lollapalooza, originally created as a traveling farewell tour for the band Jane's Addiction, first ran from 1991 to 1997, traveling across North America and inviting other musicians along the route. In 1998, no suitable headliner could be found.
