Query: Please help! Certain piano piece...name the artist/s

I don't know if anyone else noticed in the soundtrack...but there was a piano piece (excluded from the soundtrack and NOT written by Rachel Portman whom everyone seems to be so impressed with...to each his/her own) I unfortunately cannot place the exact scene it was cued. I want to say the artist/s was Cinematic Orchestra or Medeski Martin Wood. Heck, I think I even have the CD but my collection is in storage (go figure). I know that I've not given any detail but if you just take a listen I believe you'll understand why I'm searching for that particular piece. It's unbelievably moving...melancholy, and possibly sad to some. I rate the soundtrack one star because ALL the music should have been included. I'm certain there are reasons for their exclusion but I find it such an aural tease! If there is anyone out there with a keen ear for the obscure...please contact me and perhaps we solve the mystery and relieve my clouded mind.
