Not only did Björk announce that she has a new album in the works, but she also disclosed that she's been working with Arca, in a recent interview with comedian Julia Davis in AnOther Magazine. She said she and Arca, who also collaborated with her 2015 album Vulnicura, have completed three songs so far.

"Im writing my next thing," she said. "I'm still allowing myself to be a submarine; I don’t totally have the view of it yet. It's funny, each album is different for me. Like, what comes first? With this one it's maybe the melodies. This is very abstract, but the melodies have a similar kind of shape. But it's really early on, and I don't even know if I should say, but I have got three songs down with Alejandro [Ghersi, a.k.a. Arca], who I worked with on the last album [Vulnicura]. The last album, we sort of call it "hell" – it was like divorce! So we are doing paradise now. Utopia. We have done hell, we have earned some points."
