POP_UP_THEATRE  Research of artistic performances that are formed outside of linear time and space. Like transhistorical performances that create a new work by placing a contemporary object and an object from the distant past side by side. In my "real-life" career as a theater director and author, I have produced a hundred different performance forms, from classic dramatic theater and opera performances to post-dramatic and digital, or genre-based, such as children's or political manifestations. Such performances had to be perfectly performed in their expected, traditional form to fulfill their purpose - to enable my life and artistic circulation. However, in each of these plays, from the earliest projects I produced as a high school student, I implemented points that did not originally belong there. By later connecting such points, objects are created, and by connecting such objects - performance hyper objects. With the full development of digital technology, performance interfaces are created, screens with which it is possible to create a pop-up show composed of objects made in the distant past. I call such performances pop-up mysteries because their sudden performance today subsequently inscribes the meaning of the past. Like Benjamin's tiger leap into the past. The play of actors in a play in Italy twenty years ago in a pop-up performance today becomes a 3d body performed on the screen, united with texts written in Colombia that are yet to be published and music that was performed only once in Tokyo ten years ago. The Japanese students' performance is transmitted via the Zoom app to a screen in Germany where it becomes a glitch. One of the audience of such a pop-up performance experiences catharsis, but the other audience of the same performance just turns on their screens and starts watching.
