The 2026 iHeartRadio Music Festival ended on Saturday, September 19, at T-Mobile Arena in Las Vegas with a second night spanning pop, country, K-pop, rock, hip-hop and electronic music. The official billing split the festival across two days: Friday, September 18, featured BTS, Cardi B, Goo Goo Dolls, Kenny Chesney, Weezer and Zara Larsson; Saturday featured Benson Boone, Ciara, Lainey Wilson, LE SSERAFIM, Major Lazer, Muse, Snoop Dogg, a special performance by Stella Lefty and The Smashing Pumpkins.
On the final night, the clearest highlights documented by official coverage included Wiz Khalifa joining Snoop Dogg for the closing set, Lainey Wilson's tribute to Dolly Parton, Benson Boone's backflips and performances that moved across different eras of Ciara, Muse and The Smashing Pumpkins' catalogs. Below are the main highlights without mixing the two festival nights.

Snoop Dogg and Wiz Khalifa delivered the biggest surprise guest moment
Snoop Dogg's closing set featured the most prominent surprise collaboration documented from Saturday. Wiz Khalifa joined him for "Young, Wild & Free" and stayed on stage to close with "See You Again". According to iHeart, Snoop dedicated the final song to people who have lost someone, giving the collaboration one of the night's most emotional moments.
Snoop's set also reinforced the festival's retrospective approach by moving across different stages of his career and well-known collaborations. iHeart's official coverage details the closing set and Wiz Khalifa's appearance.
Lainey Wilson turned her set into a Dolly Parton tribute
Another central moment was Lainey Wilson's tribute to Dolly Parton. Wilson performed "WWDD", a song inspired by Parton, and then sang "9 to 5". The tribute appeared within a set that also moved through Wilson's newer material and established hits.
iHeart published the details of the tribute and the songs highlighted from her set.
Benson Boone opened the night with backflips and "Beautiful Things"
Benson Boone was the first artist on Saturday's schedule and brought two of his signature backflips to the festival, including one off his piano and another during the finale. The songs highlighted by coverage included "electric Blue", "Slow it Down", "Mystical" and "Beautiful Things". iHeart's report documents both the songs and the acrobatics.
Rock, pop and electronic music rounded out the final night
Muse delivered a career-spanning selection, pairing "Supermassive Black Hole" and "Starlight" with newer tracks such as "Cryogen" and "Nightshift Superstar". Coverage also highlighted lasers and LED jackets. iHeart collected photos and videos from the set.
The Smashing Pumpkins connected catalog material with their upcoming schedule. "Today" and "Edin" represented different ends of the band's timeline, while "1979" and "Bullet with Butterfly Wings" previewed material associated with the Rats in a Cage tour. Official coverage details that selection.
Major Lazer leaned into a rave-like production with fire, lights, dancers and remixes, along with "Lean On" and "RoTATe". Before taking the stage, members said they were preparing a new album and mentioned February 2027 as a possible release window, not as a confirmed date. iHeart documents the set and the comments about the new project.
Ciara moved through hits from different eras, from "Goodies" and "1, 2 Step" to "Level Up" and "How We Roll". The pregnant singer kept choreography and physical performance at the center of the set. Official coverage lists the main songs highlighted from her performance.
LE SSERAFIM and Stella Lefty were also part of Saturday
T-Mobile Arena confirmed LE SSERAFIM on the billing for night two. Because the iHeart editorial coverage available at the time of this review does not detail the group's set as extensively as some of the other performers, it is useful to separate the sources: the arena's official page confirms the Saturday performance, while Ticketmaster's setlist page records six songs performed at the event.
Stella Lefty appeared as the festival's special performance. On the main stage, she sang her viral single "Boston". Earlier in the day, she had appeared at the House of Music with "Thinking 'bout You", "Why Wouldn't We" and "I Know I Know". iHeart published details of the artist's festival debut.
Night 1 vs. night 2: who performed each day

iHeart's official recap of night one helps keep the two programs distinct. The T-Mobile Arena event page also publishes the billing by night.
Where to find official records after the festival
The event was livestreamed on Disney+ and Hulu and broadcast through iHeartMedia stations in more than 150 U.S. markets. After the festival ended, the safest place to revisit specific moments is iHeart's official coverage, which keeps articles with photos, videos and artist-by-artist highlights. Availability of a full on-demand replay on streaming platforms can vary, so it should not be assumed without a current confirmation.
