Billboard -- Mumford & Sons ' acoustic guitars may have some company on their next album.

"We're not going to be the band that stands for folk music or for organic music," band frontman Marcus Mumford told the UK's Sunday Times. "We've always done what feels good, rather than what we've thought long and hard about, and we'll do whatever feels soulful next, whether that's with an electric guitar or a synthesizer."

"It's dangerous for us to talk about what we've been discussing for the third album, but we do have greater ambitions not to just stay within certain sonic confines," Ben Lovett added.

The group's certainly done well with their current arrangements: "Babel," the UK act's sophomore album, moved 600,000 in its first week this fall, the second-biggest bow of the year after Taylor Swift's "Red." The album scored them six Grammy nominations for the upcoming awards show, including Album of the Year and Best Americana Album.

Rather than rest on their success, the group's already back at work on its next release, prepping new songs -- and perhaps, exploring new instruments -- at a rehearsal studio.

"They're bones of songs, but really exciting bones," the band's Winton Marshall told NME earlier in December. "Sturdy bones."
