First a live blog, then a photo gallery, and now you can actually watch pro-shot footage of Metallica's set at the Big Four show at Yankee Stadium. The band has posted the below video, which features footage from soundcheck, the band's meet-and-greet with fans, the full performance of "Blackened," the Big Four jam of Motorhead's "Overkill," and more. You can watch the full video below.

This past Wednesday, September 14, was a historic night for heavy metal. The Big Four of thrash -- Metallica, Slayer, Anthrax and Megadeth -- took the stage at Yankee Stadium for arguably the biggest, most-anticipated metal show the East Coast of the United States has ever seen.

As is now customary, last night's Big Four show at Yankee Stadium featured a "jam" with members of all four bands -- Metallica, Megadeth, Slayer and Anthrax -- taking the stage to perform a classic song. Usually, the track has been Diamond Head's "Am I Evil?," but last night, the bands played a song they had never before played together: Motorhead's "Overkill."

The Big Four. Anthrax, Slayer, Megadeth and Metallica. Not only are they our November cover stars, but it just so happens that today, September 14, they're playing just their second-ever U.S. show at Yankee Stadium in the Bronx, NY.
