Which country hosted Metallica's September 28, 1991 concert at Tushino Airfield?

The Soviet Union hosted Metallica's September 28, 1991 concert at Tushino Airfield.

The Moscow performance took place during the band's 1991 touring period and was described as the first free outdoor Western rock concert in Soviet history. It followed the release of Metallica and became one of the most famous large-scale concerts associated with The Black Album era.

Attendance estimates vary substantially. Contemporary and retrospective accounts commonly place the crowd somewhere between 150,000 and 500,000 people, while unofficial estimates have reached much higher figures. Because the numbers are disputed, the country is the clearest single answer.

The concert occurred only weeks after Metallica's August release and during a period of extraordinary political change. The Soviet Union formally dissolved in December 1991, so references to the event correctly identify the host country at the time as the Soviet Union rather than modern Russia.
