iHeartRadio Music Festival To Bring Back ‘House Of Music’ Fan Experience.

The iHeartRadio Music Festival is adding an extra layer of star-powered fan engagement with the return of the House of Music presented by Hyundai. The free, two-day activation will take place Sept. 19-20 outside Las Vegas’ T-Mobile Arena, where festivalgoers can explore more than a dozen interactive rooms inspired by this year’s performers.

The installation coincides with the festival’s two-night lineup, which includes Ed Sheeran, LL COOL J, Mariah Carey, Maroon 5, Tate McRae, Lil Wayne, Jelly Roll, The Offspring, Tim McGraw, and more.

This year’s House of Music includes immersive experiences tied to artist catalogs and new releases. Fans can step into Ed Sheeran’s playful “album world,” recreate LL COOL J’s “BAD” album art and graffiti wall, celebrate Mariah Carey’s latest projects, revisit Maroon 5’s “Songs About Jane” era, and take part in Tate McRae’s music video-inspired runway.

Ahead of Saturday night’s main stage, Julia Michaels will perform inside the House, including a debut of her new single “No Heartbreaks Killed Me Yet,” dropping Sept. 19.

Fans will use a scannable QR “House Pass” to unlock digital activations, earn points, and qualify for prizes, including festival tickets and meet-and-greets. Hyundai returns as presenting sponsor, joined by Capital One, Arm & Hammer Power Sheets, Audible, belVita, Lenovo Legion, and others.

“The House of Music continues to evolve each year, and this year’s experience is our most immersive yet,” iHeartMedia’s Tom Poleman and John Sykes said in a joint statement. “It’s a celebration of artistry and connection, where fans can step into the creative worlds of their favorite performers and engage with music in a way that’s personal, playful, and unforgettable.”

As previously announced, the 2025 iHeartRadio Music Festival will be hosted by Ryan Seacrest and broadcast live nationwide across iHeartMedia stations in more than 150 markets. Hulu will once again serve as the exclusive livestreaming partner.
