16 track ‘Collection’ which brings together tracks which have never before appeared on an Alison Krauss album including material from off soundtracks (eg ‘Down To The River To Pray’ from the ‘O Brother Where Art Thou’ soundtrack) and five previously unreleased tracks. There are duets with Sting, Brad Paisley, James Taylor, John Waite and my particular favourite her vocal/fiddle duet with Natalie MacMaster of ‘Get Me Through December’.
