Last month, the xx said that they were in the studio recording the follow-up to their 2012 album, Coexist. At the time, they shared a Spotify playlist of songs that have been inspiring the new album, and they’ve continued to update it over the last few weeks with songs from artists like Perfume Genius, Arca, Floating Points, Cat Power, Christine And The Queens, and more.

And just a few hours ago, as IndieSpot points out, the playlist was updated with a mysterious new track that is attributed to two dashes and bears an all-white cover. It’s 55 seconds of ambient noise with some voices peeking through that very well could belong to the xx members, and Spotify displays a Young Turks copyright label on the track.
