A great track by Harold Azmed.

This time it is harder to find a genre a priori, so just try it out in your game to realize whether it works or not. Also it has many variations and changes which makes the track great, but if it is hard to make it fit your game consider looping as a helpful technique.

This track is off the beautiful album Altar Soundtracks, one of Harold Azmeds great Soundtrack albums. There are also some other works by Harold Azmed posted on OpenGameart.org, so check them out.
