This was the first show performed in 2011 and the first U.S. gig featuring The Big 4.

It has been almost three years since the last large outdoor gig in the U.S. The last large outdoor concert was Ozzfest in August of 2008.

This was the first time that the band performed in Indio, CA at the Empire Polo Club.

While the first half of the song was performed at two shows in 2005, this was the first time that the full version of Orion was performed in the U.S.

Metallica brought out members of Slayer, Megadeth, and Anthrax to perform a cover of Diamond Head’s Am I Evil?. Dave Mustaine, Kerry King, Scott Ian, Rob Caggiano, Chris Broderick, David Ellefson, Frank Bello, Charlie Benante, Shawn Drover, Dave Lombardo, and Joey Belladonna all participated in the jam.
