The British indie trio announced that they have been working on new music material in an Instagram post celebrating the new year.
"Looking forward to 2020! We've all been working on new music, can't wait to share it with you! Hope you have the best new year!" they wrote, alongside a black-and-white photograph of bandmates Romy Madley Croft, Jamie Smith and Oliver Sim.
Details about the forthcoming project are still scarce to this date, although The xx first alluded to their much-anticipated fourth studio album back in August.
In a sit-down with Matt Everitt for BBC Radio 6 Music, bassist and vocalist Oliver Sim revealed that he had been working separately with his fellow bandmates on the follow-up to their 2017 "I See You."
"I've done a lot of work with Romy in the last couple of weeks. I've done a lot of work with Jamie, but we haven't had that moment yet of all three of us being in the room together," he explained.
Since then, the three musicians have been busy working on music for other artists.
Among them are pop sensation Dua Lipa and supergroup Silk City, for whom Croft co-wrote her latest collaborative single "Electricity."
The British singer-songwriter also penned the 2018 hit "More/Diamond Ring," in which Benny Blanco teamed with Ty Dolla $ign and 6lack.
Meanwhile, beatmaker Jamie Smith, who also goes by Jamie xx, produced Mark Ronson and Miley Cyrus's latest collaboration, "Nothing Breaks Like A Heart."
More recently, The xx joined forces with Belgian fashion designer Raf Simons for a special capsule collection marking the 10th anniversary of their debut "xx" album.
Last September, the London trio signed an emergency climate campaign by Music Declares Emergency, alongside the likes of The 1975, IDLES, and Nadine Shah.
