Halloween weekend is about to get a whole lot louder. BOO Seattle 2026 is returning to WAMU Theater on October 30–31, bringing two nights of bass, house, spooky surprises, and some seriously stacked talent to the Pacific Northwest. If you haven’t figured out your Halloween plans yet, consider this your sign.
With three massive themed stages, over 50 DJs and performers, and plenty of surprises lurking around every corner, BOO Seattle is shaping up to be one of the most exciting Halloween EDM festivals of the year.
A Halloween Lineup Worth Screaming About
Let’s talk about this lineup because BOO Seattle did NOT come to play.
Friday, October 30, kicks things off with an incredible mix of artists, including GRiZ, GRAMATIK, DJ Heather, Casey Club, Levity, and Ravenscoon. Whether you’re looking to get lost in some funky grooves, dance to house music, or absolutely throw down to bass, Friday has a little something for everyone.
And somehow, Saturday might be even crazier.
Saturday, October 31, brings Subtronics, Sara Landry, Cloonee, A Little Sound, Getter, and The Masquerade to the stage. From heavy bass to hard techno and infectious house beats, Halloween night is going to be absolutely unhinged in the best way possible.
More Than Just the Music
One of the best things about BOO Seattle is how fully it embraces Halloween. We’re talking elaborate stage production, creepy visuals, incredible costumes, and an entire venue filled with ravers ready to celebrate spooky season.
With three uniquely themed stages to explore, there’s always something new waiting around the corner. It’s the perfect excuse to get creative with your festival outfit, grab your rave fam, and spend Halloween weekend dancing until your feet hurt.
See You in the Shadows!
