What a show.
Mumford and Sons need no introduction. They brought the banjo into modern pop-rock, and cemented their place on the charts with good harmonies, writing, and lyrics. And we’ve all been told excitedly by a teenage girl at a party how the band members can each play all the instruments, ever. We all recognize the opening riff to The Cave, and will automatically sing along to Little Lion Man, albeit without quite hitting all the notes and harmonies.
