Universal Music will release "The Big Four: Live From Sofia, Bulgaria" DVD and Blu-ray containing footage of the June 22, 2010 Sonisphere cinecast from the Sofia, Bulgaria leg of the touring rock festival featuring the "Big Four" of 1980s thrash metal — METALLICA, SLAYER, MEGADETH and ANTHRAX. The DVD hits the streets on October 15 in Northern Europe, October 18 in most of the rest of the world, October 19 in North America and the full shows from all four bands will be included in the two-disc set along with behind-the-scenes and interview footage. In addition to the two-DVD set and the corresponding Blu-ray, there will be a limited-edition "super deluxe" box set including the DVD set, five CDs with ALL the music, a 24-page booklet, a poster, photos of each band, and a "Big Four" guitar pick.

METALLICA was joined onstage during the show by members of MEGADETH, SLAYER and ANTHRAX for a performance of the DIAMOND HEAD song "Am I Evil?"

METALLICA frontman James Hetfield, MEGADETH singer/guitarist Dave Mustaine and ANTHRAX vocalist Joey Belladonna took turns singing the song, which has been a part of METALLICA's live set for decades. The event marked the first time that Dave Mustaine had performed onstage with METALLICA since April 9, 1983. An original member of the band, he was fired just weeks before METALLICA recorded its debut album, "Kill 'Em All".

Mustaine, who was replaced by Kirk Hammett, went on to form MEGADETH and achieve worldwide success on his own.

He still harbored a grudge against METALLICA, however, with some of his feelings coming out in an intense scene with drummer Lars Ulrich in the 2005 documentary "Some Kind Of Monster".

According to Billboard.com, the Sonisphere cinecast from Sofia was beamed via satellite in HD to cinemas and was seen by more than 100,000 fans. It was distributed globally into hundreds of cinemas by New York-based BY Experience.

In the U.K. it was screened in 79 cinemas. "At the Odeon in Leicester Square in London there was a mosh pit, and at the end of the show they had a stage invasion, which is just phenomenal to even think about," promoter Stuart Galbraith told Billboard.com.
