Problem statement
Robert Wilson, a prominent American director and designer, is considered one of the most influential figures in this movement. Since the 1970s, he has created works that fundamentally transformed conventional narrative structures through his unique combination of visual elements, music, lighting, and scenography. Unlike many of his contemporary directors, Wilson relies less on spoken language or complex dialogues and emphasizes visual expression, the rhythm of movements, light, and music. For this reason, many critics consider his works to be a kind of “visual theater” or “visual opera.” A distinctive feature of Wilson’s works is their extensive reliance on technical-performance elements. By employing advanced lighting techniques, creative use of color, minimalist but meaningful set design, and the integration of music and electronic sounds, he has been able to create a different experience for the audience. In fact, by transferring the semantic load from the dramatic text to the technical and visual elements, Wilson has blurred the boundary between traditional theater and multimedia experience. Such an approach allows his performances to be evaluated not only as dramatic narratives, but also as “living paintings” or “moving paintings.” Among Wilson’s works, two performances are of particular importance: the play “Einstein on the Beach” (1976) and the play “Death, Destruction and Detroit” (1987). Einstein on the Beach, the result of Wilson’s collaboration with contemporary composer Philip Glass, is considered one of the turning points of postmodern theater. By breaking with the classical structures of opera, replacing linear narrative with visual and musical structure, and utilizing rhythmic repetition of scenes, this work creates a completely new experience for the audience. In this play, Einstein is presented not as a historical figure with a specific biographical narrative, but as a symbol of science, time, and multilayered realities. Sharp white lights, symbolic images, and minimalist music all serve to create a dreamlike world and interpretive imagery.
On the other hand, “Death, Destruction, and Detroit” takes a different approach, but one that is in line with the postmodern worldview. In this work, Wilson recreates a political space, but without presenting an explicit political message. Using everyday signs, symbolic scenes, and visual space-making, he somehow reflects politics on the level of signs. This play is more about politics in the conventional sense than it is an attempt to show how politics permeates the everyday lives of contemporary people. Thus, Wilson offers a new understanding of the relationship between art and politics not only through the language of the text, but also by using the language of the image and technical techniques. The necessity of studying Wilson's works and his way of using technical-performance factors lies in the fact that postmodern theater would be incomplete without understanding such experiences. If modern theater, emphasizing text and narrative, represented the world in the form of stories, postmodern theater seeks to represent the world through signs, images, and multisensory experiences. Wilson's works show a prominent example of this transition. With visual expression, he allows the audience to be not only a listener of the narrative but also a spectator, participant, and even interpreter of meaning.
Research Objective
 This research aims to study the use of technical and performance factors, including light, color, music, and staging, in Robert Wilson's works. The main focus is on two plays, "Einstein on the Beach" and "Death, Destruction, and Detroit."
Research Question
 The main question is how Robert Wilson used technical and performance factors to produce postmodern theater content and, through them, transformed the traditional structures of narrative and drama.



Research method                                             .
This research is an applied research based on its purpose and a descriptive-analytical research based on its nature and method. The present study is an applied research of the type of case study that was conducted by analyzing the application of the semiotic technique. In this respect, this research attempts to explain the effect of visual elements on the audience through a case study of Einstein on the Shore and Death, Destruction, and Detroit by Robert Wilson.
In this study, library research of relevant scientific sources and case studies of two of Wilson's executive works were used                               .
The analysis method of the present study is qualitative-reference with a descriptive-analytical approach, and the sampling method is selective (because the type of sample size requires that the sampling be selective so that we can examine it accurately). The variable in this type of research is not defined.
Conclusion
Robert Wilson’s works use elements of dance, music, visual arts, and traditional theater. This alternative method of theater production changes the dynamics of the viewing experience and the way the audience perceives the world. In Wilson’s theater, the spoken word exists to work with visual aesthetics, not to dominate them. Wilson experiments with the aesthetics of the stage and the role of the written text. In postdramatic, which forces a thought process, there is a theatrical experience that reveals the issue raised by the production and the results of the connection of each element and person. The play is based on a famous beach photograph of Einstein, and in this world of images, Einstein’s life and theories are also revealed. Thanks to this, the fact that the light that would have been simply wasted reveals many truths on stage. The author suggests going to see a postdramatic work to avoid the impact of these interruptions on the audience. In this way, you will see how every known element remains unknown and how, in this unknown, it is forced into a thought process and is constantly released on stage. Finally, from the present study, we conclude that light, movement, and energy are the benefits of space that bring Wilson's theory of relativity to fruition. On the other hand, Einstein's dreamlike vision can be reflected in the images created on stage and in the light and music. Also, in the play Death, Destruction and Detroit, a political space is shown without specifying the political message, through everyday signs that show the links between the essentially unseen war in Germany and the cover of American culture. Wilson interprets politics as the postmodernists do, not as the political deeds of great men, but as part of the everyday life chain of political experience seen in the streets.
