Last month, the xx announced a fall tour and shared a playlist of songs they've been listening to in the studio while at work on their next album, including Frank Ocean, Radiohead, Solange, Cat Power, and more. Now, a mysterious new track has been added to the playlist: a 55-second-long interlude not credited to any artist, as Indiespot points out. It has an xx vibe, but has not been confirmed to be new music by them. Listen to it below.

The xx’s last album, Coexist, was released in 2012. Jamie xx’s 2015 solo album In Colour featured both of his bandmates, Romy Madley Croft and Oliver Sim.
