"Though NCPA’s opera house can pack only some 2,000 people, I hope millions of people can enjoy the concerts through the broadcasts," Chen says.

"At Berlin’s Waldbuhne, people can bring champagne, salmon and caviar, making the forest a giant picnic area. Now, imagine, you are shopping at The Place, or just taking a walk with friends passing the square, you can stop in front of the screen to listen to a beautiful melody. Or if you live close to one of the screens, you can bring a seat to enjoy the whole concert."
