Gotta love it
Every time I hear this loop I think of the little intro in Leo and Satan II (naturally) and smile, simply because it contrasts Satan as shown in the movie, at least most of the time. The sacrilegious chanting was a nice touch, and the percussive sounds complemented it nicely. For me, the guitar was a bit too much when it sustained the whammy effect. Just rather distracting for me. Also it could have been a tad longer, as there are many ways it could have built up to more tension.
I think I have to go watch that movie again. Awesome work!
