The Big Four: Metallica, Slayer, Megadeth, Anthrax

The "Big Four", Metallica, Slayer, Megadeth and Anthrax are bringing their historic European tour to the global stage by beaming the event via satellite to movie theaters around the world in a special HD cinematic event. These four legendary acts broke out of the underground thrash movement in the 1980's to dominate the metal world, selling millions of records and packing arenas across the globe.

Despite huge demand, these musical giants have never shared the same stage until now.

The legendary June 22, 2010 concert from the tour's stop of the Sonisphere Festival in Sofia, Bulgaria will air the same day in over 450 theaters in more than 140 markets in the U.S., as well as beamed into theaters in Europe, Canada and Latin America. Delayed screenings are planned in Australia, South Africa and New Zealand.
