She was one of the secret guests at Hyperdub's midweek club night.
The event was the third edition of Hyperdub's monthly residency, called Ø. The only artist officially billed was Jesse Kanda, who had an installation in Room One and performed in Room Two. One attendee told RA that Björk's set, which took place in a room filled with dry ice, "started with five minutes of birds tweeting, weird storm sounds and drone noises" before "warming up into more club-type tracks," with Björk "pitching up and pitching down acapellas of pop songs." Arca, one of the night's other surprise guests, regularly got on the mic to hype her. As FACT note, the other surprise guests included Shannen SP and Mica Levi.
Take a look at some photos from the party.
