This is one of those movies made so they could show a 5 minute scene. It's a two-hour yawnfest interrupted by one of the best (and few) mecha sword duels ever. Of course, this is the soundtrack to that scene. Watch the battle here.
I love this song with all my heart because it was one of the first epic soundtracks I listened to, back when I was in high school. Its clean and vibrant strings are truly sublime. I could only compare them with The Flight of the Lord of Flies, by Therion. I should post that song someday.
