As mentioned previously, Justin Vernon (Bon Iver, Volcano Choir) is producing The Staves’ upcoming sophomore album If I Was  (due February 2nd on Atlantic).  The sisters recently got together with The Line of Best Fit and performed song Open off of their interim Blood I Bled EP.   Check their one-take performance below in all its pristine and evocative glory.  After watching Open, check out the group’s trailer for If I Was.  We can’t wait.
