'Sleep Alone' serves as the lead track from their new album Beacon and is released on September 3 via Kitsuné.
The track, which will be unveiled on Radio 1 tonight (July 19) at 7.30pm, will be available to download for free at twodoorcinemaclub.com for 24 hours only.
Discussing the LP, which was recorded in LA with acclaimed producer Jacknife Lee (Bloc Party, U2), Alex Trimble said: "Beacon is a much more intimate record than our first, but at the same time, it's much bigger and more inclusive.
"Working with Jacknife Lee was a joy and a pleasure. He shared our goals and played a huge part in putting the pieces together in the right way."
The band recently released the artwork and tracklisting for the record, which is out the same week as the single.
