1 hour ago 3

Walker & Royce, Space Laces, it’s murph, James Hype, Sara Landry, Westend, and more have been added to this year’s BOO Seattle lineup.

Spooky Season is still months away, but Insomniac is getting everyone prepped for the frightful festivities ahead. The behemoth brand is set to head back to the Pacific Northwest for the upcoming edition of BOO Seattle on October 30-31, and began building hype in May by announcing that GRiZ and Subtronics will headline. Today, more details have been revealed about what’s in store for attendees heading to WAMU Theater on Halloween weekend by dropping the second phase of the lineup.

There’s an onslaught of bass artists joining GRiZ and Subtronics at the festival who will surely turn heads. Levity, Space Laces, TroyBoi, Samplifire, Ravenscoon, The Masquerade, Vastive, YDG, and Casey Club will all deliver a wallop of wubs when they take the stage. Gramatik is also slated to perform, bringing his funky style, while A Little Sound drops some drum and bass into the mix.

Those looking for a dose of house and techno have a range of options available. Standouts like Walker & Royce, Taiki Nulight, it’s murph, Joshwa, Westend, and Taylor Torrence will all throw down some groove-laden sets. If faster tempos are more your speed, you won’t want to sleep on Sara Landry, Junkie Kid, KAYZO, and CHYL. And you can’t help but have a great time when Wuki is guiding the way with his genre-bending style, while acts like Elderbook and James Hype add to the event’s dynamism.

There are still three more artists to be announced, along with other details, including on-site vendors and spooky surprises curated by Insomniac for this year’s edition. Stay tuned for that to be revealed in the coming months!
