Too sweet!
I am personally not a fan of the Kane series (nor do I know much about it) but man, was this awesome! There was just such a wonderful sense of awe and unexpectedness. It sounds a little like heavy metal. Some heavy metal sounds make the mistake of being a bit too "hard" but this manages to have a very nice grace to go with it. It never lets up for a minute, even though it is only three minutes long. My favorite part is at 2:10 when the tone seems to get darker.
I can now recognize it more as using the organ. I would be familiar with those kinds of instruments as I used to play the piano. I saw and reviewed the cartoon this was featured in and I find it odd I do not recall it. You'd think such an awesome tune would be something I could pick up well. This is not just for video game fans, but music fans!
