Guillemots have admitted that the prospect of supporting REM at stadium dates this summer is intimidating.
The Birmingham four-piece are backing The Automatic for the People legends at shows in Manchester, Cardiff, Southampton and London this summer and said providing support for a band of such esteem is both a thrilling and frightening opportunity.
Talking to inthenews.co.uk, Guillemots frontman Fyfe Dangerfield stressed: "It's definitely exciting because they're a really good band and massive!
"But it's daunting as well," he added, "as it's quite strange playing a stadium."
The lead singer of the Mercury-nominated act said a support slot is still a comfortable slot, adding: "We're not going to be the main band obviously, so we won't be playing to as many people as [REM]!"
Having played their first Glastonbury in 2007, Dangerfield and his bandmates will not be appearing at Worthy Farm this summer, instead taking the stage at the Latitude, Wireless, Connect and Hop Jam festivals.
And as far as Dangerfield is concerned, any controversy surrounding the lineup of this year's Glastonbury is "a bit boring".
"I know Noel Gallagher said something and he can be quite funny, but I don't really see what the fuss is about," he added.
"I don't think it reveals some kind of massive 'inherent racism' because it's been made into a massive deal that Jay-Z's headlining.
"I just don't really understand it - far s***ter people have headlined!"
Guillemots and Editors support REM at shows at Lancashire Cricket Club (August 24th), Cardiff's Millennium Stadium (August 25th), Southampton Rose Bowl (August 27th) and London's Twickenham Stadium on August 30th.
