Beirut will return to the UK in September for their own shows.
Justin from support band The Vaccines recently courted controversy when he said: "Glastonbury is a mainstream festival, look at how many people are here - there's like a quarter of a million people here and it's a mainstream fetival and those are three mainstream artists."
The Vaccines hit the road again this summer with a string of festival dates across Europe. They will headline their biggest dates ever, culminating in a show at the Brixton Academy in early December.
Mumford added: "With these giant shows I always feel the first few rows aren't real, There's an ecstasy that happens when you're in the front rows of a gig, it doesn't matter who's onstage, it's always a frenzy and you're squashed and you're probably quite drunk so that's not the reality. So if you can engage the furthest person back, then you can get everyone else to engage."
Butler added that it was sometimes difficult for her to create something out of nothing. "You're in the middle of a field in Germany with only mud and bread, and you have to figure out how to make a delicious meal."
They continued with 'Month of May', 'Rebellion (Lies)', 'Neighborhood #2 (Laika)', 'We Used to Wait', 'Neighborhood #3 (Power Out)', 'Keep The Car Running', 'Neighborhood #1 (Tunnels)', and 'Sprawl II (Mountains Beyond Mountains)'.
"That was the least time we've been scared doing a song we've only really played in rehearsal to 60,000 people, so thank you so much," frontman Win Butler told the crowd.
According to Butler, the band aren't planning on playing the UK "for a couple of years."
