Starts scary and slow, like the final battle or confrontation is approaching. Then, suddenly, it builds up and breaks out into a frenzy of chaotic percussion, hyper strings, and a rocking timpani and bass. Choirs swell and horns explode, the heart of the song throbbing with aggressiveness before racing to an angry conclusion. Loopable.
