They have, at the moment, the only rock album that's actually a top-10 staple on the Billboard albums chart (their debut, Sigh No More, which sits at #2), and a pair of singles ("Little Lion Man" and "The Cave") that continue to gain traction on both rock and pop radio, but the guys in Mumford & Sons aren't letting all that success go to their heads.

"We're trying really hard to enjoy ourselves, and we're doing alright," frontman Marcus Mumford told MTV News. "We've met some really nice people, met some heroes ... We feel like very small fish in a very large ocean, but it's great.

"We're a very young band," he continued. "We only have one album: We've got a lot more work to do, a lot more shows to play, but we don't want to attach our identity too much to this whole parade, because we know quite clearly what we want to do and why we do it, but we're just going to try to enjoy it."

And while they're riding high — thanks to their Grammy-show performance with like-minded pluckers the Avett Brothers and Bob Dylan (and the subsequent sales bump that performance ensured) — Mumford and his mates are trying to stay focused, not just on their upcoming run of U.S. festival appearances, but also on recording the follow-up to Sigh No More. It's really the only way they know how to cope with all the attention.

"It's pretty surreal. We're just trying to keep our heads down and figure it all out, as much as we can," bandmate Ben Lovett said. "We've been writing. ... Up in Nashville, [Tennessee,] we wrote a bunch of new tunes, and we'll continue to do that. We're going to tour them in, and when we feel ready, we'll put the second record together."

Perhaps the best thing to come out of Mumford & Sons' whirlwind run here in the States: the chance to fully absorb the American strains of folk, honky tonk and bluegrass that the Brits' debut disc dabbled in.

"The thing about Nashville that's amazing is: Everyone plays ... so you don't meet up for a drink, you meet up for a pick," banjo player (and recent trucker-cap enthusiast) Winston Marshall said. "It's an incredibly creative town, just bubbling with energy."
