As has become custom, at last night's Big Four show at Fiera Open Air Arena in Milan, Italy, Metallica invited members of Slayer, Megadeth and Anthrax onstage for the now-expected "Big Four jam." Fans expecting the bands to jam on the Diamond Head classic "Am I Evil?" were in for a surprise, however, as the bands instead played the Misfits classic "Die, Die My Darling."

You can check out video of the performance below.

You can also watch pro-shot footage of Metallica's set from the July 3 Gothenburg Big Four show here, and footage from Anthrax's set from the same show here.

The bands of the Big Four -- Metallica, Slayer, Megadeth and Anthrax -- will be bringing their show stateside for a second time in September, playing Yankee Stadium in Bronx, N.Y., on September 14.
