If you haven't got Bon Iver's album 'For Emma, Forever Ago' yet, then make it a priority. Thanks to The Guardian's Laura Barton and her piece about the album in the always great Friday Film & Music supplement, I grabbed a copy and was suitably astounded.
Also check out this video for his song The Wolves (Act I and II).
Then, check out the typically indepth and informative review from Pitchfork and you now nearly know it all.
Go get the album.
