Justin Timberlake shattered records on his collaboration with Jay-Z released last month. Now he’s looking to top the charts once more with a very different artist: Marcus Mumford.

Timberlake told England’s Capital FM that he has been working with Mumford & Sons’ frontman Marcus Mumford on some new music.

“OK, I can tell you this. There’s a Coen brothers film coming out soon that I was lucky enough to work [on] with Oscar Isaac and Carey Mulligan,” he said. “And coincidentally I did work with Marcus Mumford on the soundtrack, so I became very good friends with them.”

While he didn’t get specific about the collaboration, for their forthcoming film Inside Llewyn Davis, he did say he had a blast.

“Marcus and myself we all kind of worked on the music together and I don’t know any other world where we would have the opportunity to collaborate like that, but it was so much fun,” he said. “So not only will that be a great movie, but the music to it will be fantastic.”

It’s no secret that Mumford & Sons were inspired by the previous Coen brothers’ film O Brother Where Art Thou?.

“We gravitated [to our sound] in the sense that that was what we were listening to when we started the band. We’d come from a whole range of musical backgrounds – then we got introduced really to bluegrass and Americana, acoustic Americana honestly through O Brother Where Art Thou?,” Marcus Mumford told CBC Radio. “That movie kind of heralded the advent of bluegrass in mainstream British culture.”

Mumford’s wife Mulligan stars in the film as does Timberlake. So, while it seems a no brainer that Mumford & Sons will assist on music for the upcoming film, one can only guess what the collaboration with Timberlake will sound like. With production from T-Bone Burnett and music from the Punch Brothers, will Memphis native Timberlake find his country roots? As his style lately has been angling more 1920s jazz, it isn’t a difficult transition to imagine.
