Illenium is raising the stakes for his ODYSSEY takeover at the Sphere in Las Vegas, officially revealing the full roster of support acts while dropping his latest single, “War,” with Lø Spirit. The track arrives via Republic Records as a high-impact, fan-focused release and a darker counterpoint to recent singles like “Forever,” landing just as anticipation peaks for his nine-night Sphere run in spring 2026. Positioned as both a statement record and a bridge into his new era, “War” tightens the connection between Illenium’s emotional songwriting and the massive, cinematic scale of his upcoming residency.

“War” finds Illenium leaning into a guitar-driven, rock-edged sound that blends indie rock, alt-pop and his signature melodic heaviness. Lø Spirit’s vocal cuts through with raw urgency, riding bright percussion, soaring builds and explosive drops that feel custom-built for the Sphere’s 360-degree immersion. The song first sparked buzz when Illenium road-tested it at Apocalypse Festival in Long Beach, with fan-shot clips going viral and pushing expectations higher for ODYSSEY. He has highlighted “War” as a personal favorite, noting how its darker tone opens a new lane in the narrative he is building around the album and live show.

On the live front, Illenium has now confirmed the special guests who will help anchor ODYSSEY at Sphere across March and April 2026. The first weekend leans heavy into festival pedigree, with Brazilian star ALOK, Dab The Sky and Wooli joining the bill. Later dates bring a bass-focused closing run featuring SLANDER, DJ Diesel (Shaquille O’Neal) and Tape B, alongside additional names like Levity, Audien and Ray Volpe across the residency. Across nine shows set for March 5, 6, 7, 12, 13, 14 and April 2, 3, 4, the Sphere will be the only place fans can experience the ODYSSEY album live, with custom visuals and sound design created specifically for the venue’s format.

Coupled with “War,” the full support reveal signals that Illenium is treating ODYSSEY not just as another tour, but as a flagship chapter in his career. Between the exclusive Sphere production, the cross-genre support lineup and the darker, more aggressive edge of “War,” he is clearly positioning this run as the definitive expression of his next era – one built to push his blend of melody, storytelling and scale to a new level for EDM fans worldwide.
