This one of several tracks on Vulnicura that was produced by Venezuelan producer Arca, (aka Alejandro Ghersi, who previously worked with Kanye West and FKA Twigs). He told Fader how he came to work with the Icelandic artist. "A while ago, [Björk's manager] reached out to me, and very respectfully and gracefully expressed that she liked [2013 mixtape] &&&&&—in a very pure [way] and without any expectation," Arca explained. "I couldn't have ever expected that, I was so happy."
"We wrote back and forth a few times, and she finished her tour here in London and asked me if I knew anyone who could DJ for a casual after-party," he continued. "I volunteered, of course, and this weird electric thing happened. I felt so comfortable around her, and it developed from there. We met up one time to see if there was some kind of possible chemistry [between us] and sure enough, there was. I've learned a lot from every musical collaboration I've ever had, but there's something about my relationship with Björk that is special to me."
