“Scientists at the State Hermitage Museum in St Petersburg have been examining how concerts by the Rolling Stones, Paul McCartney and others in the adjacent Winter Square have affected their collections over the past three years. The unpublished findings, they say, could affect the future of rock concerts staged at stately homes. The preliminary results of the three-year study, being examined by the Grabar Art Restoration Institute in Moscow, show that every 10 concerts above 82 decibels add an extra year to the age of a work.”
