Mumford and Sons performed new tracks, 'Believe' and 'The Wolf' on Saturday Night Live last night.

Following a short hiatus, the folk lovers have returned with a more modern, electric sound and have ditched the tweed and banjos for leather jackets, skinny jeans and an altogether more plugged-in sound.

The two tracks are set to appear on their forthcoming album, Wilder Mind, the follow-up to 2012's Babel.

Check out the performances below.
