For the first time in history, the ‘big four of thrash‘ (Metallica, Slayer, Megadeth and Anthrax) can be seen on stage together. There have been shows in Poland, Switzerland and Prague already and tomorrow this super line-up will play at the Sonisphere festival in Bulgaria. Those who can’t visit one of the Sonisphere shows can visit one of the many movie theaters all over the world that will broadcast the show in Bulgaria live.
