Metallica leads the lineup of the first U.S. "Big Four" concert this weekend, scheduled for Saturday (April 23rd) at the Empire Polo Grounds in Indio, California. The lineup includes the other three bands that made up the so-called "Big Four" of mid-Eighties thrash metal: Megadeth, Anthrax and Slayer.

Still no tour planned. That sucks but I can understand how massive an undertaking it would be.

So if you can't make it this weekend, enjoy this:
