Planetary Assault Systems and Kaitlyn Aurelia Smith are also confirmed for the three-day Helsinki event.
Voimala is the biggest building in Suvilahti, a former power plant in Helsinki's Sörnäinen district. The stage is dedicated to house, techno and more leftfield electronic acts, with Nina Kraviz, Planetary Assault Systems, Model 500 (who will play live) and Shed taking top billing this year. Italian experimentalist Lorenzo Senni is also booked, as is modular synth wiz Kaitlyn Aurelia Smith, Danish artist SØS Gunver Ryberg, French techno veteran The Hacker and Finnish artist Aleksi Perälä.
RA will also present a stage at Flow this year—a new outdoor space called the Front Yard—with Willow, Jon Hopkins, Soichi Terada, Marie Davidson and more.
The rest of the festival's programming covers a broad spectrum of artists, from the likes of Aphex Twin and Jenny Hval to Young Thug and Frank Ocean.
