Mumford and Sons are about to unveil the first single from their sophomore album, 'Babel.' NME reports the Grammy-nominated folkies will premiere the song tonight (Aug. 7) on BBC Radio 1 at 7:30PM London time — that's mid-afternoon here in the States.

The name of the single is unknown, but the guys have revealed the full 12-song tracklist for 'Babel' on their website. The album opens with the title track and includes songs titled 'Whispers in the Dark,' 'Ghosts That We Knew,' 'Lover of the Light' and 'Broken Crown.' 'Babel' hits U.S. retailers on Sept. 25.

NME reports that the band said in a statement, "We are more than excited to release 'Babel' into the world. We had started writing new songs well before we got into the studio to record. At first, we peeled ourselves off the road quite reluctantly. We love playing live, obviously, but it had also become an important part of our creative process, we had been writing and rehearsing in soundchecks, and sort of 'road testing' new songs on our very gracious audiences."

They added, "As a band, we've never been closer or more collaborative, all working to our strengths. And so we feel that this record is a natural progression that we’re proud of, and we cannot wait to take it out on the road."

'Babel' was produced by Markus Dravs, who was at the helm for Mumford and Sons' smash debut, 'Sigh No More,' which has sold more than two million units in the U.S. The group is touring the U.S. through Sept. 1 and heads to Australia in October.
