The clip was made for virtual reality headsets. Bjork writes:
This came about as a spontaneous fruit of mine and andrew huang’s collaboration . we had already done black lake , the “family” moving album cover and the black lake “book cover” trailer and then found us in iceland one day with nothing to do and a 360 camera lying about. We discussed its potential for intimacy and andrew then suggested we take it to the beach where the song was written. It immediately rang true for me as that location has a beautiful 360 panoramic view which matches the cyclical fugue like movement in the song. If the song has a shape it is sort of like a circle that just goes on forever. i had recorded the strings with a clip on mike on each instrument. We have made a different mix where we have fanned this in an intimate circle around the listener. So as you watch this in the virtual reality headset it will be as if you are on that beach and with the 30 players sitting in a circle tightly around you.
If you watch the video using Chrome, you’ll get a little control button that will let you spin the camera angle around.
