John Talabot, Matthew Dear, Dixon and Actress are also among those booked for the festival in Seattle.
Based on the names announced so far, this year's addition is likely to have the most diverse (and robust) lineup so far in the festival's nine-year history. Headliners include house and techno artists like Carl Craig, John Talabot, Matthew Dear, Roman Flügel, Nina Kraviz, Dixon and DVS1.
A lot of leftfield acts have been confirmed as well, such as Actress, Fennesz, Andy Stott, Cut Hands, Demdike Stare and local artist The Sight Below. Ambient pioneer Biosphere is confirmed, and Robert Henke will perform under his own name and as Monolake. On a more indie tip, there's Not Not Fun artist Maria Minerva and Ariel Pink's Haunted Graffiti.
