The subject of research in this article is the artistic practices of modern Russian Germans, implemented within the framework of the cultural festival “German Sloboda”. It is proved that festival artistic practices belong to the “culture of ethnos” (according to V. G. Babakov’s classification), that is, they are a combination of ethnic and externally introduced components. The latter are the artistic practices of postmodernism, such as performance, happenings, environment and their varieties. The scientific novelty of this work is the consideration of the traditional culture of Russian Germans in the context of artistic forms, methods and techniques of modern times. The objectives of the work include: an analysis of the artistic practices of the cultural festival of Russian Germans “German Sloboda” from the point of view of correlating ethnic content and modern forms of its presentation, as well as the development of the above-mentioned artistic practices in the history of the festival. To achieve the set goals and objectives, a historical-genetic method is used, which allows us to trace the relationship between ethnic traditional and modern innovation in artistic practices, as well as a structural-functional method that demonstrates the artistic practices of modern Russian Germans as an integral part of their spiritual culture. As a result of the analysis of the artistic practices of the cultural festival of Russian Germans “German Sloboda”, a conclusion is made about the culture of modern Russian Germans as a synthesis of the immanent and transcendent, as a combination of following the sociocultural experience of previous generations – traditions – and the desire of the current generation for changes – innovations. The “culture of ethnos” of modern Russian Germans is in the stage of modification and transformation of its forms, creative experimentation, search for an individual-personal beginning with constant reliance on the collective traditional experience of the past. The seven-year history of the cultural festival of Russian Germans “German Sloboda” clearly demonstrates the active use of postmodern artistic practices, in which art leaves traditional spaces (galleries, museums, concert or theater halls) and conquers new spaces that are not necessarily associated with art.
