BOO! Seattle has unveiled its monstrous 2025 lineup, bringing a massive wave of electronic talent to the WAMU Theater this Halloween season. Set for 31st October and 1st November, the Insomniac-produced festival returns with a two-day program that blends bass-heavy chaos, house grooves, and spine-tingling production.

Leading the bill are headliners Zedd, Marshmello, Nero, RL Grime, and Vini Vici, with strong support from high-calibre names like Black Tiger Sex Machine, Dimension, Ben Nicky, Virtual Riot, and Kill The Noise. Drum and bass legends Flux Pavilion and Doctor P will also team up for a back-to-back performance, while Boys Noize, Noizu, and Panteros666 promise infectious energy on the dancefloor.

Also featured are a host of rising stars and genre-blurring acts, including Mersiv, Southstar, Alyssa Jolee, Mall Grab, Genesi, and Lauren Mia. From house to dubstep to experimental bass, BOO! Seattle continues its tradition of showcasing diversity and innovation across its Halloween celebration.

Tickets for BOO! Seattle 2025 go on sale this Thursday, 24th July at 12pm local time. With a history of quick sellouts and high-octane performances, fans are encouraged to secure their spot early for one of the Pacific Northwest’s most beloved Halloween raves.
