BOO Arizona is making its return to WestWorld in Scottsdale this Halloween weekend, with Insomniac dropping the Phase 1 lineup for the festival’s first Arizona edition since 2019. The highly anticipated two-day event is scheduled to run from October 30–31, 2026.
The initial lineup spans a wide range of the electronic music spectrum, promising a diverse experience for attendees. Confirmed acts include the dynamic Mexican-American artist Deorro, the high-energy dubstep artist Level Up, and the Australian hard dance sensation Restricted. Joining them are the GRAMMY-winning duo The Chainsmokers and the multi-platinum producer Zedd. Organizers have confirmed that additional names will be announced in the coming weeks.
The festival will spread across two stages and feature immersive, haunted mansion-themed production, perfectly setting the stage for a spooky Halloween weekend. Insomniac is billing this as one of the most ambitious editions of BOO Arizona to date.
Reflecting on the atmosphere of the event, the official festival 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 description 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 via the official festival website.
