We will eventually be getting a physical CD on sale with the soundtrack for those who want to collect it via Lulu.com, but for those who want the soundtrack in MP3 format (it's available in the game's directory in .ogg format anyway) I set up this zip file.
The music is by Walter Eres (my father) and Long Dao (a friend I met in the Ohrrpgce community); my father composed most of it and Long composed two or three tracks as well as arranging/orchestrating the rest of them. He's a pretty good remixer, I believe he has one on Overclocked Remix for those familiar with that site.
http://studioeres.com/immortal/soundtrack.zipIt's 44 MB, so it may take awhile to download. It contains about 30 minutes of music.

Two tracks from the game do not appear in this collection. The stage select song by
Helen Humes, and the final ending song by Crazy Mary (it's available on
their website). Neither of those two was created for the game, although we did have permission to use the latter (my mother's boyfriend is part of that band) and the former is in the public domain and out of copyright.
"A Winter's Journey" wasn't finished in time for the initial v1.0 release and is to be added with v1.1, along with the level editor, so it may be unfamiliar to most players. It's the 'final battle' music (currently the final battle just uses the normal boss music).
