What Should Performers Do When Audience Members Are Using Their Phones?

Just a few nights after Anne-Sophie Mutter stopped a concert to tell a woman in the front row to stop filming, actor Joshua Henry, star of a new Off Broadway musical called The Wrong Man, tried to get a man in onstage seating to quit filming. The man paid no attention. So Henry “reached into the seats, deftly grabbed the phone out of the man’s hand, wagged it disapprovingly, and tossed it under a riser — all mid-song, without skipping a beat. ‘I knew I had to do something,’ he explained later.” – The New York Times
