Lollapalooza has always one of the premier music festivals in the country. The Chicago festival has just released its 2015 lineup, and it’s a fantastic one. Headlining with be the legendary Paul McCartney along with Sam Smith and Metallica. The festival will take place in Chicago’s Grant Park from July 31st through August 2nd, and features an almost absurd amount of fresh acts.

This year marks the 10th anniversary of the Chicago festival. While Lollapalooza has technically been around since 1991, it was originally only launched as a farewell tour for Jane’s Addiction. Though the success of the festival began waning in the late 90s, the festival found great success once choosing its home in Chicago.

Other great acts from this year’s festival include TV on the Radio, Alabama Shakes, and Gary Clark Jr. Unfortunately, three day passes for the festival have been sold out for quite some time. On the bright side, additional one-day tickets are set to go onsale today, March 25th at 10am. Be sure to check out this festival, because a lineup featuring Paul McCartney and Sam Smith is one that you don’t want to miss.
