Firefly Day Four Highlights: Waka Flocka Flame Fires Up the Crowd, Jared Leto Passes Out Popsicles & More

The fourth and final day of Firefly (June 18) ended on a strong, rock-heavy note with sets from Thirty Seconds To Mars and Muse -- and a more alternative rock sound from The Shins. While earlier in the day, simultaneous sets from Waka Flocka Flame and Hamilton Leithauser (on two very close by stages) proved slightly problematic as Waka's rowdy set distracted at times from the more mellow, indie set from Leithauser.

Most impressive of all, though, was the clear and star-filled sky that covered the festival grounds each night -- proving the less-than-ideal forecasts wrong. Weather aside, here are the (music) highlights from day four of Firefly.  

Waka Flocka's Dedicated Fans

"Is weed legal in Delaware?" questioned Waka Flocka Flame's DJ and hype man DJ Whoo Kid. "We want to know before we smoke onstage." Soon after, Waka appeared, energetically jumping around during his featured tracks like Machine Gun Kelly's "Wild Boy" and during pump-up hits like Chief Keef's "I Don't Like," French Montana's "Don't Stop" and more while the massive crowd went wild. He tossed water bottles out to fans -- even with the intense winds the heat was still strong -- and later said: "I get a lot of DMs that say, 'Don't perform, just party.'" Fortunately, for the fans at Firefly, Waka did both.

Hamilton Leithauser's Subtle Sass

Hamilton Leithauser's set largely overlapped with Waka's, and their stages were in very close proximity to one another. As a result, the booming bass bled over into Leithauser's set, which prompted him to ask, "Are we still competing with that racket over there?" He then performed one of his (even) softer songs, "1959" off the 2016 collaborative album between Leithauser and Rostam Batmanglij, I Had a Dream That You Were Mine. The indie singer-songwriter (and former frontman of The Walkmen) also showcased his pure and warm tone while performing the album's two biggest hits: "A 1000 Times" and "In a Black Out."

Thirty Seconds To Mars' Prop-Packed Performance

Jared Leto appeared to be performing for his own amusement just as much, if not more, than for his fans in the Echelon. Dressed in a floor-lengthy, emerald green kimono, sunglasses, and a camouflage hat, the singer (and actor) treated the first 10 minutes of the rock group's set like its last. He instructed the crowd to crouch down, to sit on each other shoulders, crowd surf and more. In return, he tossed out popsicles, had confetti burst into the air and dropped hundreds or large, colorful balloons into the crowd (all of which immediately blew away due to the strong winds). While Leto performed "This Is War" and "Kings and Queens" from the stage -- as most artists do -- he eventually found his way to the sound booth, in the middle of the field, to perform an acoustic version of "The Kill (Bury Me)."

James Mercers' Return To Firefly 

The Shins' frontman -- and now sole vocalist -- James Mercer last performed at Firefly in 2014 with his side project Broken Bells, a duo with consisting of Mercer and producer Danger Mouse. "It's really good to be back at The Shins this time," Mercer said with a subtle smile. The set couldn't have been slated for a more fitting hour, considering the sun was just setting behind the woods when Mercer sang the lyrics, "Step into the night," from "Saint Simon." Elsewhere, he included a handful of The Shins' most favored hits, like "Caring Is Creepy," "Australia," "Kissing The Lipless" and many more. Mercer made sure The Shins' most recent album, Heartworms, received plenty of attention, too, as he not only sang tracks like "Name For You" and "So Now What" but also performed in front of a backdrop reminiscent of the LP's cover art: a colorful, floral skull. 

Muse's Delaware Debut

"It's our first time in this beautiful state," Muse frontman Matt Bellamy told the crowd who then roared as a welcome of sorts. While Firefly managed to make it through an entire four day festival with nothing more than a light rainfall on Saturday (July 17), Muse made sure to conjure up a storm on stage during its headlining set on the Firefly stage with heart-pounding drumming -- acting as thunder -- and an eye-catching light show -- serving as strikes of lightening. The explosive rock set saw Bellamy (who was wearing Kanye-esque shutter shades) deliver powerful vocals on everything new, like "Dig Down" (the group's latest single released last month), and old, such as "Resistance" off 2009's The Resistance, "Hysteria," off 2003's Absolution​ and, of course, its most commonly known hit "Supermassive Black Hole."
