Basically, performers own a Copyright on their images...of their faces, instruments, etc. If they do not defend that Copyright-if they let anyone, and everyone photograph them-they lose the copyright. Then, they won't get paid big money to be photographed by pros to endorse: food, candy, beer, clothes, cars, etc.
Then they shouldn't give a free performance in a public park. No different if they were walking down the street and someone took their photo.
