 Conceptual art, Minimalism, Earth art, and Performance art mingled together to expand the very definition of Art.By the late 1970s, many of the graduates of the school of the arts in Cuba, "the Facultad de Artes Plasticas of the Instituto Superior de Arte" (founded in 1976) were going to work as schoolteachers, teaching art to young Cubans across the island.This provided a platform for the graduates to teach students about freedom of expression in medium, message, and style of art.
