Music fans invaded Chicago’s front yard this past weekend (Grant Park) for the 2015 version of Lollapalooza. IE ‘s Curt Baran roamed the grounds to go after shots of big names like Sir Paul McCartney, Gary Clark Jr. and Alabama Shakes. Of course, we’d be remiss if we ignored Lolla’s always excellent undercard which featured Spookyland, SZA, James Bay (performing and candid), Black Pistol Fire, Misterwives, St. Paul & The Broken Bones, Father John Misty, Broods, Tove Lo and IE August issue cover stars MS. MR. Oh, and Flying Lotus brought a U.F.O. to perform in. Here’s Day 1. Have yourself a look.
