The metal giants have never before all shared the same stage, despite huge demand. But on June 16, 2010, METALLICA, SLAYER, MEGADETH and ANTHRAX will take to the Sonisphere stage at Bemowo Airport, Poland, to make the dreams of headbangers the world over become a reality. A third "Big Four" appearance is planned for Sonisphere Czech Republic three days later, with more Sonisphere shows featuring the awesome combo to be announced in the coming days and weeks.
