This was played at my video game music concert in Paris, 05/05/12. While commenting, please keep in mind that I had to play an hour and a half of live music!
Now for the slightly scary and mysterious piece. That repeating left hand figure and those sudden right hand starts and stops really make the ambience. My favourite part is in the middle, when the right hand kind of goes "WHOOOOOSH!", those scales make a windy effect.
