More than four years since the release of their last album Coexist, it appears The xx may soon have new music to share. 

Although it's unclear if they have completed their new full-length, they've been in and out of the studio for much of the past two years. And a source with knowledge of the production process tells Variance new music in some form "could actually be out before the holidays" if all goes as planned.

The new material, which would be the first since their 2013 Great Gatsby soundtrack contribution "Together," is said to sound "different from what some fans may be expecting."

As we previously mentioned, producer-musician Jamie xx expressed hopes last fall the band would release music sometime in 2016. In December, they revealed on Facebook they were going into "winter studio hibernation."

While The xx hasn't released an album since Coexist in 2012, both Romy Madley Croft and Oliver Sim contributed to Jamie xx's debut album In Colour, which arrived last year and was among Variance's 50 Best Albums of 2015.

Additionally, Madley Croft contributed to OneRepublic's new album Oh My My, having co-written and performed guitar for the song "Fingertips," which was produced by Ryan Tedder and Benny Blanco. The album is out Friday (Oct. 7).

The trio is also set to co-headline Lollapalooza's South American festivals next spring alongside Metallica, The Strokes and The Weeknd, with dates in Brazil, Chile and Argentina.  

A rep for The xx did not immediately respond to a request for comment.
