The American Family Insurance Amphitheater got its second headliner for Summerfest 2027 on Monday, when the festival announced that Mumford & Sons will play the big stage on Friday, July 9.
This will be the second time that the meteoric U.K. band have occupied the brightest spotlight at Summerfest, although they’ll find that things have changed quite a bit since their 2013 show at what was known then as the Marcus Amphitheater. They were touring behind sophomore album Babel at the time and have since released four more studio efforts, most recently 2026’s Prizefighter.
While that record will get its share of attention when Mumford & Sons play the AmFam Amphitheater at next year’s Summerfest, the band will no doubt trot out a cross-section of their considerable discography during the July 9 performance. Tickets for the show go on sale to the general public at 10 a.m. this Friday, Nov. 13, online via Ticketmaster and at the Summerfest box office.
Artist bio
Mumford & Sons formed in London in 2008 and quickly became one of the biggest British acts of their generation, topping album charts around the world, rising from intimate clubs to festival headliners, and earning multiple Grammy and BRIT Awards.
The band entered a new chapter with Rushmere in March 2025, followed less than a year later by their acclaimed sixth studio album, Prizefighter, which debuted at No. 10 on the Billboard 200. Featuring collaborations with Hozier, Gracie Abrams, Chris Stapleton and Gigi Perez, the album found the band at their most instinctive and open, capturing the sense of community and connection that has defined them from the beginning.
In 2026, Mumford & Sons brought Prizefighter to audiences worldwide with their biggest North American tour in years and were the subject of Mumford & Sons: The House Band, directed by Sam Jones, which premiered at the 2026 Tribeca Film Festival. The documentary follows the beloved British folk-rock group aboard a one-of-a-kind train tour, playing their own songs, backing an extraordinary roster of guest artists and embracing the kind of spontaneous performances that remind audiences why live music still matters.
Mumford & Sons have long harboured a strong sense of community, collaborating over the years with artists including Bob Dylan, Bruce Springsteen, Neil Young, Pharrell, Maggie Rogers and Brandi Carlile. Through numerous creative evolutions and studio experiments, the band have cultivated an unmistakable sound that continues to influence and inspire generations of artists around the globe.
