Mumford & Sons recently released "Guiding Light," returning with their first release in three years.
To celebrate their new music and Delta album announcement, the UK rockers played a surprise set outside of one of London's iconic art galleries. Much like Mumford & Sons, London's Tate Modern gallery is known for its innovation and creativity.
The pop-up set came while the band was filming an upcoming "Guiding Light" music video, delivering a quick performance for the crowd with new and old songs.
