Mumford & Sons went unplugged at a homecoming gig in London for the Apple Music Festival.
The band's four leading members turned off their microphones & sang Cold Arms, accompanied only by Marcus Mumford's acoustic guitar.
Numbering just a few thousand people, the audience at the Roundhouse in Camden fell silent as the group sang in close harmony for the track from their latest album Wilder Mind.
The intimate performance towards the end of their 90-minute set was in stark contrast to the rest of the gig, which was typically energetic & passionate.
Mumford told the audience: "It's nice to be back in our home town. It's satisfactory to be playing in the UK again."
Despite the majority of the set being made up of songs from their latest album, it was Little Lion Man from their debut record Sigh No More that received the loudest cheer from the audience during the encore.
Mumford compared the gig to recent performances at Reading & Leeds, saying: "There was a lot more vomit & unprotected sex." He then joked: "I think I prefer … Oh I don't know."
The gig was the penultimate night of the festival, for which fans win tickets in local prize draws. Mumford & Sons were supported by the British solo artist Jack Garratt, who joined the headliners on stage for a version of the Eurythmics hit Sweet Dreams.
Mumford said of Garratt: "He's going to rule the world & we're very pleased approximately that."
Florence And The Machine, supported by James Bay, will draw the 10-night festival to a close on Monday.
