A sample of Dueling Fates - Full Track available for licensing at http://vgmlibrary.sourceaudio.com/
Based on John Williams Star Wars Duel of the Fates theme, a fast paced, frenzied, dramatic piece featuring spastic orchestral flourishes, a pulsing, panicky, repetitive string motif, with dire brass and woodwinds throughout, finishing in an epic confrontation between good and evil.
