The xx appear to be teasing new music after a 55-second long composition appeared on Spotify as part of the playlist that the band have been sharing while they work on their third album, due next year.
The track was quietly added to the playlist and is currently untitled and without artist credit, but it is copyrighted to Young Turks, the label with whom they have released music since their debut album in 2009. You can check the track out via the embed below.
