Kayzo performs at the BOO Seattle electronic music festival, an Insomniac Halloween event in the SoDo neighborhood.
Kayzo plays the WaMu Theater on Friday, October 30, from 5 PM to 1:30 AM. He's part of BOO Seattle, Insomniac's annual Pacific Northwest Halloween electronic music festival, which returns in 2026 for its fifth edition. The festival runs across three stages and covers house, bass, techno, trance, dubstep, and hard techno, with four themed areas and a haunted-mansion concept. Costumes are encouraged, though full-face makeup that obscures your ID and outfits resembling public safety uniforms are restricted. General admission is 18+, and alcohol and VIP areas are 21+.
Kayzo is the main feature of the night, and the festival's wide range of styles means you can drift between the different stages throughout the evening. The haunted-mansion theme runs through the whole thing, and the costume encouragement is a big part of the vibe, so it's the kind of night where showing up in a full outfit is the norm rather than the exception. Just keep the ID and uniform rules in mind before you commit to a look.
