Insomniac has unveiled the second phase of its BOO Seattle 2026 lineup, adding a substantial wave of artists to the Halloween weekend event scheduled for October 30–31 at WAMU Theater in Seattle, Washington.
GRiZ and Subtronics were confirmed as headliners back in May, and the newly announced additions span a wide range of electronic genres. On the bass music front, Space Laces, Ravenscoon, Samplifire, Troy Boi, The Masquerade, Vastive, YDG, Casey Club, and Levity are all set to perform. Gramatik joins the bill bringing his funk-influenced sound, while A Little Sound will represent drum and bass.
The house and techno contingent is equally stacked. Walker & Royce, it’s murph, Westend, Taiki Nulight, Joshwa, and Taylor Torrence are among those confirmed for groove-driven sets. For attendees who prefer harder and faster tempos, Sara Landry, KAYZO, Junkie Kid, and CHYL are all on the bill. Wuki, known for his genre-blending approach, is also confirmed, alongside Elderbook and James Hype, who round out the announcement.
Three additional artist slots remain to be filled, and Insomniac has indicated that further details — including on-site vendors and event-specific spooky surprises — will be revealed in the months ahead. The festival takes place at WAMU Theater, a venue that has hosted previous editions of the event in Seattle’s SoDo neighborhood.
Two-day GA and VIP passes for BOO Seattle 2026 are currently available through Front Gate Tickets.
