Behind the scenes: Insomniac and Tomorrowland’s Unity at Las Vegas Sphere

The final exhibition of the residence features Prismax’s creative technology

It’s easy to get lost in the Venetian hotel casino area, but once we hear EDM playing we know we’re on the right track. Pathways and Beats brought Subtronics jerseys and fluorescent rave braids to the intimate Sphere. Festival workers from across the US have once again gathered for a one-on-one experience under the 16K resolution electronic sky.

Tomorrowland and Insomniac, two pillars of electronic dance music known for their music festivals spanning the world, have joined together in October 2025 at the Las Vegas Sphere for Unity, for their first collaborative project. Led in part by Belgium-based production studio Prismax, a 30-person team of innovators developed new systems for the project.

The immersive screen, nearly 360-degree screen and storytelling technology is the ultimate push for video and creativity. Project Unity reimagined the fictional worlds of Tomorrowland and dedicated music festivals Insomniac. A 165-minute film, an orchestral performance and a DJ set combine animation with physical special effects for an immersive experience that can only be had at Sphere./

Collaboration between international festivals came from a simple phone call. Both Insomniac and Tomorrowland were looking to put on a show at the Sphere.

The Prismax production team created the fantastical worlds of Planaxis, Adscendo and Orbyz while Insomniac animated Beyond Wonderland, Escape Halloween and Electric Daisy Carnival. Together, they created their largest animated project rivaling a feature-length film, but with more dancing.

Prismax CEO Joris Corthout said Sphere’s resolution is 16,000 by 16,000, and this film projects 64 times the resolution of an average movie theater screen. Commissioning the project requires Prismax to build a specialized hardware infrastructure to meet its technical requirements. The team’s new farm offering supports a petabyte-sized project—more than 1 million gigabytes—and future Sphere projects.

The massive unity tree that opened and closed the show was run in real-time on the Unreal Engine, a creative tool commonly used for video games. The program allows a video jockey or VJ to go live with the player.

The seats were shaking with every drop, the sweet smell wafted in through the big vents and the fluttering butterflies reminded us of how wonderful today’s technology can be. The orchestra combined the timbre of classical instruments with the rhythms produced electronically, the environment combined with the technology and music that brought together the greats of the future. Prismax has been using technology to build experiences with Tomorrowland for 20 years and this was undoubtedly one of the most impressive yet.

Rehearsals for the show took place in a lowered “mini-sphere” in Los Angeles, but access was only granted three weeks before the show. To test the 360-degree viewing experience during the previous production stages, Prismax built a replica in virtual reality. “We [could] visit the Sphere whenever we want.” Corthout said. “When someone is ready and we want to test it, you put on the glasses and sit in the Sphere.”

At the end of the Unity film, the 20,000 Sphere attendees applauded the curtain orchestra bows. A harpist, strings, percussionists, brass and woodwinds waved to the crowd and introduced the night’s follow-up performance. The fans erupted all over the hall.

Acclaimed for pushing the limits of sound system engineering, Subtronics took to the DJ decks to perform an hour-long set of body-bending dubstep. Strong hands gripped the handlebars and seats—anything strong enough became the holy grail of dirty Subtronics drops. He gave the headbangers a break with Bon Jovi and Fleetwood Mac throwbacks, then returned to his bread and butter to give bass lovers what they really wanted.

Working under the 16K Unity Tree resolution was taken by VJ. Big bass drops and simple tempos are synchronized. The iconic subtronic cyclops also made a cameo, but this time it was 40 feet tall. “It’s all about bringing people together through music,” Corthout said.

Sphere’s dynamic storytelling inspired the creation of its twin location in Abu Dhabi. With its new hardware infrastructure, Prismax is excited to create the only place on Earth that can match its efforts.
