WATCH: First Aid Kit Covers R.E.M.’s “Walk Unafraid” with Guitarist Peter Buck

The sisters cover "Walk Unafraid" for the film Wild.

In the new movie Wild, Swedish sister duo First Aid Kit covers R.E.M.’s “Walk Unafraid” from their 1998 album Up.

The video was filmed in the woods in Portland, Oregon, where former R.E.M. guitarist Peter Buck now lives. In a classy gesture, the sisters invited Buck to join them on set, and he accepted. He played acoustic guitar while the girls sang, and the result is magical.
