Avant-garde is a term to describe the phenomenon of art and culture, resulting from the scientific and technical progress of the last century, which has distinctive and common features: deliberate, pointed experimental. Russian, in particular, Siberian avant-garde of 1960s-1980s is the art of "unofficial" movement, which is the opposition to the Socialist Realism art with its maximum sharply embodied spirit of the times. Avant-garde with no external support could be based only on personal, individual motivation. The art of Siberian artists, as opposed to Western ones, is original, individual, as it existed in isolation from the artistic life of the capital. The works of Siberian avant-garde artists presented in this paper have a general trend: they base their worldviews on the Siberian ethnic group, begin their journey in art with realism, identity, association, symbolism, philosophical reasoning about the world. After analysing the works of Siberian artists of 1960s-1980s, we can say that they laid the foundation for individual creativity in the artistic life of Siberia and Siberian avant-garde is indeed a phenomenon against the background of socialist reality. All these artists (Pozdeev, Gritsyuk, Rybakov, Makeev) are different in the themes of paintings, techniques of execution, in the direction from naive art, abstract surrealism, Romanticism to the avant-garde trance. Their works have no analogues in world art, which suggests the Siberian school of avant-garde and puts their names on a par with the wonderful artists of the twentieth century. The main feature of their works is the ability to translate images of high art complexities and contradictions of the era. Their works are an evidence of acute reflections on the contemporary world, an attempt to break through the established boundaries of the artistic thinking of the time. All this gives a positive outlook for the future development of new generations of painters, a new image of the artistic worldview. The worldview of modern Siberian artists who continue the traditions of Siberian avant-garde is a reflection of this process. Considering Siberian avant-garde as a means of human self-realization, we can talk about its ability to influence the cultural-historical process of the artistic life in Siberia.
