Audience members at a concert will be asked to judge between a Strad and a modern instrument. “At the concert on 15 September, a Nagyvary violin, built in six weeks earlier this year, and the $4 million Rochester Stradivarius, built in 1720 by Antonio Stradivari, will each be played behind a screen by violinist Dalibor Karvay. Audience members will attempt to distinguish between the two, and at intermission their guesses will be tallied up.”
