Claude says:You caught Mumford & Sons in that tight window where they were still the scrappy folk-rock upstart, not yet the stadium juggernaut—this Shepherd's Bush set captures them live in their element, all banjo snap and group-singalong energy. You dipped in and out of it through the fall and winter of 2011, returning mostly to "I Gave You All" and "Dust Bowl Dance," the kind of songs that hit different when there's a crowd behind them.
