It is well worth noticing that Anthrax and Megadeth joins Metallica on stage for "Am I Evil?" during Metallica's set (I wonder what Slayer were doing? I only see Dave Lombardo on the snare – maybe they don’t play sissy commercial junk like Diamond Head?), and also that Anthrax supposedly does a Ronnie James Dio tribute playing a snippet of "Heaven and Hell" during "Indians".
Of course, once I get my grabby little hands on this, a thorough review will be posted.
