Justin Bieber closed out the Billboard Hot 100 Music Festival, his first concert appearance in two years, to the delight of screaming fans at Nikon at Jones Beach Theater.
"Do you want to hear some new music?" teased Bieber, who ultimately did perform his recent single with Skrillex, "Where Are Ü Now." "Well, too bad."
Instead Bieber reworked some of his more familiar hits. He put more focus on his vocals for "Boyfriend." He added an a cappella bit to "As Long As You Love Me."
He also reminded his screaming fans why they liked him in the first place, showing off his dance moves as well as his acoustic ballads, such as "Be Alright."
"It's been a while since I've done a show," Bieber said. "Miss me?"
Bieber actually seemed to miss the crowd. "I've got some songs to play tonight, but I just want to talk to you," he said.
The second day of the Billboard Hot 100 Music Festival at Nikon at Jones Beach Theater Sunday was way bigger than the first, record-breaking day, though it did show some growing pains.
More than 23,000 fans packed the venue Sunday, giving the inaugural festival attendance of more than 40,000 for the weekend -- another record for Nikon at Jones Beach Theater.
Earlier, superstar Nicki Minaj's set was delayed 30 minutes by sound issues, then briefly set back again when her microphone went out. But she came back, charging through a hit-filled set and changing the lyrics in "Super Bass" to say she's "got a thing for Long Island guys."
"You know I'm from Queens, right?" Minaj said after asking the crowd who was from Long Island. "It feels damn good to be home."
She was followed by EDM titan Skrillex, whose energetic DJ set was marked by his massive light show and fog blasts -- and several references to New Jersey. At one point, he cut the lights onstage and ordered the crowd to hold up their cellphones, sending an ethereal glow of tiny screens three stories high.
The lines for everything at the music festival -- from food to simply entering and exiting the stage areas -- seemed much longer Sunday. The two-day extravaganza at Nikon at Jones Beach Theater involved three stages and a 10-hour lineup of acts.
Sunday afternoon, rapper Fetty Wap had the Beach Stage packed with thousands of people packed shoulder-to-shoulder to hear his current hits, including "Trap Queen," which the crowd shouted along with him.
"I like this energy," the New Jersey rapper said, as the crowd chanted his name. But Wap leaped from the stage during the last song in his 30-minute performance, injuring two girls whose legs appeared pinned under a steel fence. The rapper returned to the stage and apologized to the crowd before repeating the lyrics.
Meanwhile, The Maine, a six-piece alternative pop rock band from Phoenix, seemed thrilled to draw a large crowd to the Samsung Level Stage.
"Thanks for showing up and not making this awkward," lead singer John O'Callaghan said, encouraging everyone to dance. "Don't be afraid to explore the space."
The band played "English Girls" and "American Candy," among other hits.
"These guys are incredible," said Alex Jundanian, 23, of Boston. "I love the way they shred."
Next came the EDM duo The Chainsmokers, who packed the stage area to capacity. Despite the sun beating down on the crowd, the main heat came from the fans reacting to jams including "#SELFIE," "Kanye" and "Let You Go."
Norwegian DJ Kygo dazzled, lining the front of the main stage with a row of tall flame-shooters that blazed as copious amounts of confetti showered the crowd.
On Saturday, more than 17,000 turned out to see 10 hours of music on three stages, including current king of the Billboard Hot 100 charts, The Weeknd. The R&B singer not only played his current No. 1 "Can't Feel My Face," but also surprised the crowd with a rocking version of Beyoncé's "Drunk in Love."
The festival's opening day went so well that John Amato, president of the music industry trade magazines Billboard and the Hollywood Reporter, said he expected the festival to return next year.
Sunday night, Madison McCandless, 9, wasn't tired waiting late into the night for Justin Beiber to hit the stage at Jones Beach -- she was just straight-up amped.
"He's a great singer; I'm excited!" the West Islip resident said shortly before 10 p.m.
Her mother Kim McCandless, 43, brought her four daughters -- ranging in age from 9 to 16 -- an "end-of-the-summer treat" before school starts, she said.
Heidi Mueller, 17, of Massapequa Park was eagerly awaiting the arrival of Justin Bieber in her mezzanine seats.
"I just might cry," she admitted. "I haven't seen him in so long. He's really special."
