The Killers turned Chicago’s Grant Park into one giant singalong at Lollapalooza on August 4, 2017, delivering a masterclass in stadium rock built on indie grit, new wave synths, and pop anthemics. Frontman Brandon Flowers worked the massive crowd through a setlist stacked with staples, “Mr. Brightside,” “Somebody Told Me,” and “When You Were Young,” then tipped his hat to his influences with covers of Muse’s “Starlight” and The Smashing Pumpkins’ “Disarm.” It stands as proof of why the Las Vegas natives remain one of the most reliable and exhilarating live acts of their generation.
