2026 iHeartRadio Music Festival Closes With Snoop Dogg, Muse, Ciara, And Major Lazer In Las Vegas

On Saturday, September 19, Las Vegas became a meeting point for several generations and genres of popular music. Inside T Mobile Arena, the second and final night of the 2026 iHeartRadio Music Festival brought together established stars and newer performers for a showcase that moved from rock and hip hop to country, K pop, R&B, and electronic music. Benson Boone opened the final night, while Snoop Dogg, Muse, Ciara, Lainey Wilson, LE SSERAFIM, The Smashing Pumpkins, Stella Lefty, and Major Lazer were among the performers featured throughout the evening.

The September 19 finale completed a two night festival that began Friday, September 18. The overall lineup included BTS, Cardi B, Goo Goo Dolls, Kenny Chesney, Weezer, Zara Larsson, and other prominent artists. Hosted by Ryan Seacrest, the festival took place at T Mobile Arena in Las Vegas. Performances were also made available through Disney+ and Hulu, while iHeartMedia radio stations provided festival coverage to listeners across the United States.

A Festival Built Around Musical Variety

The second night demonstrated the broad scope of the 2026 iHeartRadio Music Festival. Benson Boone began the evening with an energetic performance that included the acrobatic backflips that have become part of his live appearances. His opening set helped establish the fast moving format of the night, which gave audiences a chance to experience performers from several corners of contemporary music.

Muse later brought its arena rock sound to the stage with songs including “Supermassive Black Hole” and “Starlight.” The Smashing Pumpkins also reached into their extensive catalog, performing recognizable tracks such as “1979,” “Bullet with Butterfly Wings,” and “Today.” Together, the two groups gave the final night a strong rock presence alongside the event's pop, country, hip hop, and dance performances.

Country star Lainey Wilson introduced another musical direction to the program. Her set included “Wildflowers and Wild Horses,” “4x4xU,” and “Heart Like a Truck.” Wilson also performed “9 to 5” as a tribute to Dolly Parton. The performance connected a contemporary country star with one of the genre's most recognizable songs and added another generational link to the evening.

Ciara delivered a set centered on familiar hits including “Goodies,” “1, 2 Step,” “Like a Boy,” and “Level Up.” Her appearance highlighted the festival's ability to bring recognizable songs from different periods of modern pop and R&B into the same program.

LE SSERAFIM, meanwhile, represented the international reach of K pop at major American music events. The group's presence on the final night followed BTS appearing as part of the festival's opening night lineup. Their inclusion showed how global pop acts continue to share prominent American festival stages with established performers from rock, country, hip hop, and R&B.

Snoop Dogg Welcomes Wiz Khalifa

One of the evening's notable surprises arrived during Snoop Dogg's performance. His set drew from songs associated with different stages of his career, including “Gin and Juice,” “Drop It Like It's Hot,” and “Who Am I? (What's My Name?).”

Snoop Dogg then welcomed Wiz Khalifa to the stage for “Young, Wild & Free.” Wiz Khalifa remained for “See You Again,” creating one of the final night's major guest appearances.

The collaboration reflected an important part of the festival format. Instead of presenting a traditional concert built around a single performer, the iHeartRadio Music Festival places numerous artists into shorter sets across a tightly scheduled program. Surprise guests can add another layer to that format, giving the live audience performances that may differ from what they would see during a standard tour stop.

Major Lazer provided another shift in atmosphere as the festival approached its conclusion. The group performed outside T Mobile Arena as part of a special closing set. The performance included “Lean On” and helped extend the celebration beyond the main arena as the two day event reached its end.

Why The 2026 iHeartRadio Music Festival Stood Out

The significance of the September 19 finale came largely from the range of music presented to the same audience. Rock groups with decades of history appeared alongside contemporary pop performers, country artists, hip hop veterans, electronic acts, and K pop stars.

That variety offered a compact picture of the modern mainstream music landscape. Audiences no longer experience major artists only through traditional radio or individual concerts. Streaming, social media, live events, and digital platforms have created more opportunities for listeners to move between genres and discover performers from different markets.

The festival's distribution also extended its reach beyond Las Vegas. With performances available through streaming platforms and radio coverage around the country, the event was designed for an audience much larger than the crowd inside T Mobile Arena. That combination of a physical concert, national radio programming, and streaming access illustrates how major entertainment events can now reach audiences across several formats at once.

For music fans, the final night offered another reminder of what large multigenre festivals can provide. Familiar catalog songs shared space with current performers, international acts appeared alongside American stars, and surprise collaborations gave the event moments unique to the festival setting.

With the September 19 finale complete, the 2026 iHeartRadio Music Festival added another chapter to its annual Las Vegas run. For audiences following today's pop culture landscape, the event provided a broad snapshot of artists, sounds, and generations currently sharing the mainstream music stage.
