- Kentucky Speedway, Sparta, USA - Mastertarium pt.1 (Metallica featuring Serj and Daron SoAD)

James Hetfield was not able to attend this concert; therefore, Metallica enlisted the help of Daron and Serj from System of a Down to help them perform Mastertarium (Master of Puppets Sanitarium) on stage. This is a phenominal performance. Serj does not know the lyrics, you will see in this video.
