I'll edit this post and write more later, but it's really great. And the credits are like a who's who of indie (and other) rock. (At various times, most of the New Pornographers, Kurt Heasley of the Lilys, Nora O'Connor, Kelly Hogan, Calexico (and their former Giant Sand-mate, Howe Gelb), M. Ward, Lucy Wainwright Roche, and Garth Hudson (plus others who are probably in famous bands but whose names I don't recognize).
And I don't know who Paul Rigby is, but he co-arranged nearly all of the songs, and it all sounds beautiful.
EDIT: Not much more to say actually except that I love the Piano Orchestra concept (check the lengthy NY Times profile of her for pictures/description: LINK)
Also, my favorite thing is that she covered a song by SPARKS. I am going to a post on them at some point soon because they're awesome and not very well known.
