Insomniac announces Griz and Subtronics for BOO Seattle 2026

It may be the beginning of festival season, but Insomniac Events is already thinking of the spooky season months away. Last month, Insomniac Presents released two huge names for this Halloween’s BOO Seattle music festival at the WAMU Theater. Insomniac announced GRiZ and Subtronics as its first two major artists performing on October 30 and 31 for Seattle’s biggest Halloween rave of the year.

This special release came just days after GRiZ and Subtronics held their first-ever Griztronics at the Gorge, a two-day festival at the biggest venue in the Pacific Northwest. Many attendees reported significant difficulties entering both the campgrounds and the venue. Long lines and significant wait times led partial refunds for both general admission and VIP ticket holders.

High demand and ticket costs for Griztronics at the Gorge caused many fans to miss the chance to attend. Thankfully, Insomniac Events is giving us another opportunity to see these two EDM all-stars this October. Starting this month, Insomniac is offering a special twenty-dollar down payment for payment plans, aiming to keep the event more affordable and accessible to those on a tight budget.
