One of, if not the best vocal pieces on the site, up there with Knuckleduster. Interestingly enough, from the same series. The instruments were great too, and I definitely got that mortality feel. A very emotional piece, well done.
I haven't played Metroid Prime in a while and the source tune escapes my memory, but from what I hear it's a very nicely balanced piece of work. Easily something to jam to while working. Added to playlist.
