The free Monsters of Rock show happened on September 28, 1991, barely a month after the failed coup attempt that shook the Soviet Union. The Black Crowes and Russian band E.S.T. were also on the bill.
Nobody agrees on how many people were there. The official VHS release said 500,000. Other estimates go as high as 1.6 million.
Either way, it's one of the biggest crowds rock has ever played to.
