Metallica have commemorated their first-ever U.S. Big 4 show by releasing their headline set as a downloadable album.
The show, which took place at Indio, California on April 23, featured a rare run-through of the Cliff Burton instrumental Orion, which originally featured on the band's seminal 1986 album, Master Of Puppets. It was the first time the band had ever played the song in its entirety in the U.S..
Metallica also brought out members of Slayer, Megadeth, and Anthrax to perform a cover of Diamond Head's 1980 classic 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 took part in the all-star jam.
The headline set is now available from the band's official site www.livemetallica.com.
The Big Four will play Sonisphere at Knebworth on July 8.
