Each day of Firefly has loosely favored a musical theme. The opening schedule revolved around loose, electronic pop a la Glass Animals and K.Flay; day two hammered home the guitar-driven aughties with Weezer, AFI, Franz Ferdinand and OK Go; Saturday introduced a hip-hop heavy bill fronted by The Weeknd and Chance the Rapper. Yesterday’s finale appropriately embraced grandiose rock ’n’ roll pageantry, with Phantogram, Muse and Thirty Second to Mars bringing the epic. (Some jangly Shins pop offered a brief respite, too.) Of note, Phantogram incorporated some gorgeous Swiss design backdrops, backlit basic shapes and lines with solid fills of white and black—visuals reminiscent from their current opening group, Tycho. In sharp contrast, Muse went full-on neon ‘80s, including light-up Max headroom glasses. Indefatigable photographer Julia Drummond preserved the theatrics in the gallery above, including Jared Leto in a memorable floral smock. Check back tomorrow for our final Firefly gallery, with backstage portraits from our favorite performers.
