The not-really-a-video video accompanying Mumford & Sons’ new song shows the road endlessly moving beneath the camera. “I Will Wait” is the first taste of Babel, the British band’s follow-up to 2009’s Sigh No More, and it’s definitely a son of previous Sons: a harmony-draped bluegrass-pop anthem, lushly arrayed with horns, banjo, and fiddle. But the road imagery isn’t quite Dukes of Hazzard. “Touring so much and playing so many different kinds of places, especially big ones, affected how we hear ourselves as a band,” Mumford vocalist and multi-instrumentalist Ben Lovett told SPIN recently about the new record, due out September 24 on Glassnote. The earnestly sung, unshowy lyrics suggest the challenges of keeping up a romance when there’s romance in the life of a band playing a new city every night, too. After the brisk strums fade out, the video flashes the text, “ROAD TO RED ROCKS,” where the band will be playing two sold-out shows August 28-29. They won’t have to wait much longer.
