OHO is considered one of the most interesting, complex and important examples of post-war avant-garde art in Central and Eastern Europe. After achieving major success as one of the first from Eastern Europe to exhibit at New York's MoMA, the group disbanded in 1971. OHO was not just an art collective but a unique cultural phenomenon that explored the visible and the immaterial through art, philosophy, sociology, science and coexistence with the earth and nature. Already in the 1960s, the group was raising relevant questions about anthropocentrism, ecology and the economics of the art. This documentary about OHO by Damjan Kozole is rich in never-before-seen archival material and, for the first time, comprehensively presents this inspiring phenomenon of intertwining art and life. - Slovenian Film Database
