This track is set to be part of a mini LOTR suite on Kaitlyn's new album FilmSong. (The rest of the suite is arranged by Kim Scharnberg.) Though the album is not yet on shelves, you can already purchase "Into the West" as a high-res MP3 download. Click here for the 192kbps version ($0.99) or here for the 320kbps version ($1.49).
I'm not poised to make a dime off this, incidentally, just presenting it as a public service announcement. I'm sure the completists out there will not want to be without this unique arrangement.
