This article covers some new forms of publicness in the field of art culture of the Russian city of Perm, e.g. dramatics as a performance in a street environment, and synthetic museum-theatrical form under the conditions of a stage box. The study was accomplished mainly via culturological method. At one time theatre left the urban environment, but in the 21st century theatrical forms have begun to permeate urban space again, the statement primarily concerns site-specific theatre. This is equivalent to the birth of new theatrical-city publicity, a new modality of the interpenetration of the public and the private. One of the best-known theatrical projects in this field is ‘Remote X’ (‘Rimini Protokoll’ band). Here, the close co-existence habitual to city dwellers turns into a social substrate, and a way to implement interpersonal artistic communication, thereby largely changing the disposition of the former, and transforming itself. Another new form of relationship between collective and individual aspects in the public sphere is the synthetic museum-theatre form, on the example of immersion dramatics ‘Permian Pantheon’ (Perm Academic Theatre, stager Dmitry Volkostrelov). The natural ‘calendar-seasonal’ tempo-rhythm of the dramatics creates a triple semantic effect risen from artistic reality. It immerses the viewer into the process of traditional subsistence in whole (actualisation of the cultural collective unconscious), represents cultural phenomena (which corresponds to the culture-focused paradigm of artistic consciousness of the second half of the 20th century to the early 21st century), reaches the level of worldview values, the philosophical generalisation of cultural-existential reality. Thus, on the example of two Perm theatrical plays the author can speak about the origin of new forms of publicness in contemporary culture to entail new relationships between publicity and privacy in the current realities.
