BOO Arizona Returns in 2026 With Zedd, The Chainsmokers & More

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 two-day event runs October 30–31, 2026.

The initial lineup spans a wide range of the electronic music spectrum. Confirmed acts include Mexican-American artist Deorro, dubstep artist Level Up, Australian hard dance act Restricted, GRAMMY-winning duo The Chainsmokers, and multi-platinum producer Zedd. Additional names are still to come.

The festival will spread across two stages and feature haunted mansion-themed production — fitting for a Halloween weekend event. Insomniac is billing this as one of the biggest editions of BOO Arizona to date.

Heavily themed around the calendar date that the festival chose as home base, their website reads, with respect to their layout: “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. 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 go on sale Wednesday, July 8 at 12pm MST at arizona.boo-halloween.com.
