Watch The Staves perform an acoustic version of "Open" in session with 3ème Gauche

We premiered the cut last month, saying that "the sister's voices stand out as a highlight as they weave stellar, mesmerising harmonies, gradually ascending to a monumental climax in unison. It's emotionally wrought, but never maudlin. There's an ounce of hope to discover."

Those harmonies are brought closer to the forefront as they strip back the other elements of the track for the barebones performance.

The Justin Vernon-produced LP If I Was is released 2 February on Atlantic.

Watch the session below.
