One of the most important exponents of contemporary art in South America, Helio Oiticica creates multimedia room installations which intertwine social themes, experimental elements, and appropriations from popular culture, film, and music. This book focuses on works which have rarely been seen elsewhere, works in which Oiticica questions the traditional relationship between the audience and the world of the movies, such as his "quasi-cinemas," which combine slide projections and music. The lavish nine-part sequence "Black Experiments in Cosmacocoa" is published here for the first time, alongside Oiticica's own notes and critical texts.
