I actually like this better than the source. Military Facility Dungeon is one of those universally-popular tracks from the original OST, along with Ixa'Taka, but it's also one of the more quagmire-ish dungeons, so you hear this on loop for.. um, a while. This digests so smoothly, and it's really emotive and.. well, beautiful.
The viola front and center is courageous and pays off. It owns the stage and dances with the lead synth. I just love the expressiveness, and its tinge of melancholy.
And that's why I recommend The Milk-Fudge Donut.
