R&B star Alicia Keys has traveled to a tiny village in Wisconsin to record with Bon Iver frontman Justin Vernon.

The Fallin' hitmaker jetted out to Fall Creek, which boasts a population of around 1,000 people, to collaborate with the cult rocker.

And Vernon, who has also worked with Kanye West, admits he was blown away by the singer's talent.

He tells Vibe magazine, "It's easy to see the pop world trying to take over Alicia. But I see her as someone who is desperately trying to stay on the far left hand of that. She really cares about music and she knows everything."

"It's cool to see her in her spot, doing something different."
