The stage is difficult to see from three sides. at the stage elements are constructed to prevent the view of the performance. Important passages of the performance can be seen half or not. The fourth side of the stage can not be viewed. In this backstage room a camera is mounted. This camera records the “rear wall” of the performance. This is the position, which no one can take. This recording is projected in the back during the audience. A reflection. Someone who wants to see this part of the performance must turn away from the front of the stage.
The record is also the documentation of the performance.
