Inspirational music

I am not sure if this is what you are looking for, but why not check out the band "Nightwish" as inspiration and possible soundtrack for the project?

They are a mix of metal and fantasy with a classically trained female lead singer. Theirs songs are found on youtube, http://www.youtube.com/watch?v=GdZn7k5rZLQ "Amaranth" is a good example, and their website is www.nightwish.com
