Metallica played the final 1991 European show supporting The Black Album at Tushino Airfield in Moscow. The concert took place on September 28, 1991, as part of the Monsters of Rock festival.
The event became one of the most memorable concerts connected with the album's early touring period. It was described as the first free outdoor Western rock concert in Soviet history. Estimates of the crowd vary widely, with commonly cited figures ranging from 150,000 to 500,000 people and some unofficial estimates reaching 1.6 million.
Metallica performed alongside other major rock and metal acts at the Moscow event. The concert came shortly after the album's August release and demonstrated how quickly the band had become a global stadium attraction.
Tushino Airfield is sometimes confused with Luzhniki Stadium, another famous Moscow concert location. The Black Album-era Monsters of Rock show was held at the airfield, which provided the enormous open space required for the festival audience.
