What we show in this book is endless live performance. Architecture is connected with music, opera and people, and then art is extended. Theatres, concert halls and opera houses belong to the main building tasks of our times. New-built, renovated and innovative soundscaping, all architects are exploring and aiming to establish a new relationship between art, people and buildings for contemporary life. In this book, we select different performance architectures from the world; some of them are set up first, and others reborn with stories and bright future. All of them are cityscapes in their cities.
