ILLENIUM Unveils Full Sphere Lineup and New Single “War” with Lø Spirit

The Illenium Sphere takeover just got bigger. Illenium has revealed the full roster of support acts for his ODYSSEY shows at the Sphere in Las Vegas. At the same time, he dropped his latest single, “War,” with Lø Spirit. The track comes via Republic Records. It is darker than recent singles like “Forever,” and it lands as excitement peaks for his nine-night Sphere run in spring 2026. In short, “War” links his emotional songwriting to the cinematic scale of the residency.

“War” with Lø Spirit

On “War,” Illenium leans into a guitar-driven, rock-edged sound. It blends indie rock, alt-pop and his signature melodic heaviness. Lø Spirit’s vocal cuts through with raw urgency. Meanwhile, bright percussion, soaring builds and explosive drops feel made for the Sphere’s 360-degree setting.

The song first created buzz at Apocalypse Festival in Long Beach. There, Illenium tested it live, and fan clips went viral. He calls “War” a personal favorite. Moreover, he says its darker tone opens a new chapter in the story of the album and live show.

Illenium Sphere support acts and dates

Illenium has now confirmed the guests for ODYSSEY at Sphere in March and April 2026. The first weekend leans on festival stars, with Brazil’s ALOK, Dab The Sky and Wooli. Later dates bring a bass-heavy closing run with SLANDER, DJ Diesel (Shaquille O’Neal) and Tape B. In addition, Levity, Audien and Ray Volpe appear during the residency.

The nine shows take place on March 5, 6, 7, 12, 13, 14 and April 2, 3, 4. The Sphere will be the only place to experience the ODYSSEY album live. Custom visuals and sound design are built specifically for the venue.

Together, “War” and the support lineup show how seriously Illenium takes ODYSSEY. It is not just another tour. Instead, it is a flagship chapter of his career. With exclusive Sphere production, a cross-genre lineup and a harder edge, he aims to take his mix of melody, story and scale to a new level.
