Woah, this is perfect
This is probably one of the songs I like the most on NG so far, there are so many good things I could say about this, I don't know where to start. I was amazed when I read your comment after listening to the song first - sand, the desert, those really were the first things that came to my mind when I was listening to this song. The basses are perfect, the rhythm is fast and powerful enough to carry the effects well and the song just breathes dark, like you said. Dark in a cool way. This would really fit well with some villain from a movie, possibly in a chase with his foe. Another thing - this song starts of well and builds it's way up even better, doesn't let go of the tempo.
Kudos, great job.
