Alesso and Tove Lo perform during the 2015 Lollapalooza Music Festioval at Grant Park on August 1, 2015 in Chicago, Illinois.

Lolla's second day featured two very different superstar headliners, a big time collab, and a chaotic set cut short by security. Here’s Billboard’s hour-by-hour recap of the day’s highlights.

12:32 PM: Janelle Kroll gets Lollapalooza's second day started on a fitting note with her beautifully accusatory ballad "Sunny Days" at the BMI stage. "Chicago's not the East Coast, tell me about LA" she coos in her reinvention of Joni Mitchell's "Down to You (My Confidante)."

12:45 PM: Metallica fans line the barricade on the Samsung stage, wearing jean vests covered in patches and vintage band T-shirts. These diehard fans showed up hours early just to get a good spot for the band's 8 p.m. show.

12:55 PM: The second song into their set, Catfish and the Bottlemen drummer Bob Hall has technical difficulties, so Ryan McCann attempts to entertain the surprisingly large crowd for the early set time. "Our drummer's having a bit of trouble, so let's get to know each other, yeah? Always good to see each other -- especially Nicholas Cage," McCann says, referencing the floating Cage head in the audience.

1:54 PM: "This is a very sad song," explains Ryn Weaver. "I wrote it about  my grandfather." She continues, "I don't think you choose who touches you…" chuckling as the pause sets in. "… In your heart."  She launches into "Traveling Song" amid twanging acoustics.

2:03 PM: Wearing a striped tank top and black leather shorts, Ryn Weaver draws loud cheers as she sings the opening verse to "Promises." "One moooore" she lilts, while gyrating, dancing, and screaming as the song builds to its climax.

2:38 PM: Vincent Neff, frontman of Django Django, says this is his second Lollapalooza ever. The first time he came to the festival he was 15 years old and came all the way from all Ireland, his home country.

Lollapalooza 2015: Watch Performances Here!

2:45 PM: 30 minutes late, Travi$ Scott finally hits Perry's stage. His reason? "Sorry I was late. I was doing the ultimate amount of drugs."

2:50 PM: After only a few minutes, tensions are high at Scott's performance. "Middle finger up to security right now" and "If you're in a green shirt, get the fuck back," he rallies, asking fans to hop the barrier and defy the guards. Soon, the stage is overrun, and his DJ is forced to cut the music during "Don't Play." Announcements are made saying the set could pick up if everyone clears the stage, but it never happens. That's a wrap for Scott, after just a few minutes of actual performance. For more on the incident, check Billboard's story here.

Watch it all go down here:

3:51 PM: Charli XCX performs her and Iggy Azalea's "Fancy," but she sings Azelea's vocal parts as the song goes on and the crowd goes wild. Out in the crowd, dragonflies are flying everywhere, getting close to everyone's heads and making the people hoisted up on shoulders a little antsy. 

4:10 PM: Death From Above 1979 drummer and singer Sebastien Grainger returned to the festival since his last appearance in 2011. "The spirit of Lollapalooza is still alive in my purple hair," he says to the screaming crowd below him. (Grainger was a blonde in 2011).

4:11 PM: I run into a group of Metallica fans holding a spot near the front of the main stage during Death From Above 1979's set. One tells me he has seen them 12 times as they pose for a group pic. "They've got almost all the albums represented," notes an observer. He's wearing a Metallica shirt too.

One Direction -- minus Harry Styles -- was also spotted walking around the festival: 

 4:22 PM: "We can't play the original without playing the Flume remix!" holler Hermitude, as they drop both versions of "HyperParadise" before mixing into their remix of ODESZA's "Say My Name." Wearing matching hats in different seafoam green and red variants, the Aussie duo play live keyboard with their heads bobbing in unison to broken beats and heavy synth layers.

4:43 PM: RL Grime pleases a packed Perry's stage with a thundering trap rendition of Drake's "Know Yourself" while clusters of bros shout about woes.

4:59 PM: Walk the Moon jumps onto the Sprint stage, rocking out to the Lion King theme, "Circle of Life."

5:33 PM: Eli Maiman, lead guitarist of Walk the Moon, splits a hole in his jeans at the very beginning of their set from jamming too hard. "I just want to acknowledge it, and now we can celebrate it," Maiman says as he flexes for the crazed fans.

5:45 PM: Walk the Moon drops mega-hit "Shut Up and Dance" to the surprise of no one towards the tail end of their set.

6:45 PM: Boys Noize finishes strong with a rework of Nirvana's "Lithium," shearing the sound with aggressive filter sweeps and jumping on the drop as swift crossfader moves stutter the progression that follows.

7:00 PM: Long Island cult heroes Brand New come out swinging, with their new single "Mene" getting their Sprint Stage crowd into a frenzy.

7:31 PM: "Sic Transit Gloria (Glory Fades)" sounds absolutely ferocious, with a second drummer-percussionist added to Brand New's attack. Frontman Jesse Lacey and guitarist Vincent Accardi are trading frenetic, half-sung, half-screamed vocals to rev up each chorus. And the crowd is responding; mosh pits open and hands raise in unison. 

7:45 PM: Brand New ends its set -- one of the most rock offerings of the weekend -- on a high note, with Devil and God opener "Sowing Season (Yeah)." Their final set list is: 

Mene, Sink, Gasoline, Millstone, At the Bottom, Jesus Christ, You Won't Know, Sic Transit Gloria (Glory Fades), Okay I Believe You, but My Tommy Gun Don't, Seventy Times 7, Degausser, Sowing Season (Yeah)

8:04 PM: People flock to the Pepsi stage to see Banks after Kid Cudi ends his set. People stand in the street trying to get a glimpse of her sing "Beggin For Thread."

8:19 PM: "The Metallica family is here," snarls James Hetfield. "How many are virgins here?" A sizable crowd roars in response. He chuckles. "If you don't know what to do, just look at the people who have been here before.. they'll show you to have some fun here!" With heavyweight selections "Sanitarium," "One" and "Master of Puppets" in the rotation, it'd be next to impossible not to.

During Alesso's set (8:30-9:45 PM at Perry's stage) he was joined by Tove Lo, who sang her part in Alesso's hit "Heroes":

8:53 PM: Sam Smith shares with the crowd that Chicago is one of his favorite places to perform, and that today is a very special day for him -- it's his little sister's birthday. The crowd chants, "Happy birthday, Mabel," for the Smiths.

9:16 PM: Smith teaches the large crowd at the Bud Light stage some dance moves during the middle of "Restart." Left, right, twice to the side and back. The crowd picked it up in no time.

9:27 PM: Smith dedicated a few minutes of his set to Amy Winehouse by covering her "Tears Dry on Their Own," but mashed it up with Elvis Presley's "Can't Help Falling In Love."

9:55 PM: "I know I shouldn't say this, but this has been one of the most amazing festivals I've ever played in my life," Sam Smith admits, just before closing his set with -- you guessed it -- "Stay With Me."



10:02 PM: Metallica exceeds their scheduled time on a muscular series of encores that includes their deep cut cover of traditional Irish drinking song, "Whiskey in the Jar," and ferocious Garage Inc. era rework of Diamond Head's "Am I Evil." The latter prefaces a stunning rendition of fan favorite "Nothing Else Matters" that leaves fans speechless and throwing signs of the horns skyward.  A cascade of black balls signals crushing final encore "Enter Sandman." "Metallica is grateful after 34 years we're still here thank you Chicago -- thank you Metallica family!" Hetfield hollers as he finishes.
