Madonna noise alert.
Nodar Kancheli, who designed the canopy roof of the Luzhniki Stadium in Moscow, says the show's vibrations could cause it to collapse.
He said: "It could collapse if audio frequency resonates with the vibration frequency of the building. The soundwaves could damage the structure."
Kancheli was the architect of the Transvaal Water Park in the Russian capital, which collapsed in 2004, killing 28 people.
