The lecture will unveil little-known pages of the Petersburg avant-garde - from the "Union of Youth" to "Apartment No. 5". The focus will be on the artists, poets, and critics who changed the language of art, debated familiar forms, and transformed the city into a laboratory of new ideas, bold alliances, and creative discoveries. Russian avant-garde is often associated with loud manifestos, radical gestures, and names that have long entered textbooks. However, behind the familiar picture remain stories that help see the movement as alive - with its alliances, workshops, friendships, disputes, and points of attraction. This lecture addresses the Petersburg and Petrograd line of the avant-garde, where a unique artistic environment was formed in the early 20th century. Listeners will learn about the "Union of Youth" - an association of innovative artists that emerged in Petersburg before the Moscow "Jack of Diamonds". Find other events in Yekaterinburg on KudaGo.
