Recorded on borrowed banjos, and drawing on a genre deemed “un-cool” by many, Sigh No More’s runaway success could have confounded even the world’s finest trend-forecasters. It wasn’t just us Brits who went Mumford-crazy either: we could practically hear our American cousins cooing over those close-vocal harmonies from here. Everyone should be delighted to learn that Babel finds the unlikely folk idols sticking firmly to that Brit Award-winning formula. Think rollicking, fiddle-flecked, horn-embellished, stadium anthems and touching, banjo-driven ballads, with the odd cheeky expletive thrown in, ‘Little Lion Man’-style.
