Mumford & Sons rounded out their latest round of North American tour dates over the weekend with a headlining slot at Delaware’s Firefly Festival after the group played a pair of shows at New York’s Forest Hill Stadium, continuing their collaboration with Baaba Maal.

On Friday, Mumford released their new EP, Johannesburg, which was recorded with Maal, The Very Best and Beatenberg. Maal has been joining the band for live performances of album tracks “There Will Be Time” and “Si Tu Veux” during their sets, as they did at Firefly, along with a run of encore performances of “Wona” another track off the EP, which the band played at Firefly with both Maal and Beatenberg.

Mumford & Sons now head to Europe for a run of festivals and headlining dates before they return to the US for Las Vegas’ Life is Beautiful Festival, Austin City Limits and another round of tour dates around those festivals.
