BOO Arizona is making its highly anticipated return to WestWorld in Scottsdale this Halloween weekend. Insomniac has officially unveiled the Phase 1 lineup for the festival, marking its first Arizona edition since 2019. The two-day immersive experience is scheduled to take place from October 30–31, 2026.
The initial artist announcement showcases a diverse range of talent across the electronic music spectrum. Confirmed headliners and supporting acts include the dynamic Mexican-American artist Deorro, bass music powerhouse Level Up, and the high-energy Australian hard dance act Restricted. Fans can also look forward to performances from the GRAMMY-winning duo The Chainsmokers and the multi-platinum producer Zedd. Organizers have confirmed that additional names will be added to the roster in the coming weeks.
The festival grounds will be transformed across two distinct stages, featuring elaborate haunted mansion-themed production designed to elevate the Halloween atmosphere. Insomniac is positioning this iteration as one of the most ambitious editions of BOO Arizona to date.
Reflecting on the thematic vision for the event, the official site notes: “With 2 stages of paranormal frequencies and a myriad of lights that shine bright, we all come together on the dance floor to dance into the night. At the center of the mansion lies the Grand Hall, a vast ballroom of fading elegance where light drifts and shadows linger. At BOO, the night begins here, where energy converges and the biggest moments come to life.”
The narrative continues, “Lose yourself with your friends in the paranormal frequencies of a world-class lineup; a long passage that stretches beyond its limits, the Corridor. Portraits line the walls, their details shifting when not observed. Candlelight flickers without source, casting soft, moving shadows across the space. Here, you surrender to the pulse of house and techno, where sound stretches on without end and the atmosphere lingers just out of reach.”
Two-day GA and 21+ VIP tickets are set to go on sale Wednesday, July 8, at 12pm MST.
