Festival fans, gather round. We've got some interesting news for you! In 2016, Lollapalooza will celebrate its 25th anniversary of its inception. As you may know, the fest started in 1991 as a traveling affair (think Warped Tour), ended in 1997, and in 2003, found a home in Chicago's Grant Park before expanding with international editions. For one weekend a year, U.S. music nerds from all walks of life could come to the Midwestern metropolis and see the biggest names in music.

In 2006 the fine festival folk extended the party to three days, and it's been that way ever since (due to popularity and, like, how else are you going to see all relevant artists?) A decade later, in 2016, Lolla is going to be bigger than ever: Starting next year, the fest will last four days.

A four-day weekend! Don't mind if we do. Lollapalooza 2016 will take place Thursday, July 28 and continue through Sunday, July 31. Get stoked by visiting their website and click through our gallery of the best live shots taken at Lolla 2015.
