TL;DR

Insomniac has announced the return of BOO Arizona to WestWorld in Scottsdale for Halloween weekend 2026, marking the festival's first Arizona edition since 2019. The two-day event runs October 30–31 and will feature two stages with haunted mansion-themed production. The Phase 1 lineup includes Zedd, The Chainsmokers, Deorro, Level Up, and Restricted, with additional acts to be announced.

“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.”

Phase 1 Lineup Spans Electronic Spectrum

The initial roster covers a broad range of electronic styles. Zedd and The Chainsmokers lead the bill, joined by Mexican-American artist Deorro, dubstep producer Level Up, and Australian hard dance act Restricted. Insomniac has billed this as one of the biggest editions of BOO Arizona to date, with more names still to come.

Haunted Mansion Production Across Two Stages

The festival will unfold across two stages, each themed around the Halloween concept. The Grand Hall serves as the main stage, described as a vast ballroom where the biggest moments of the night will take place. The Corridor, a second stage, will focus on house and techno programming. Both spaces lean into the haunted mansion aesthetic with shifting portraits, flickering candlelight, and paranormal frequencies as the design language.

Two-day general admission and 21+ VIP tickets go on sale Wednesday, July 8 at 12pm MST at arizona.boo-halloween.com. The festival marks Insomniac's return to WestWorld after a seven-year gap.
