The Neo-Concrete Movement (1959–1961) was a Brazilian art movement, a group that splintered off from the larger Concrete Art movement prevalent in Latin America and in other parts of the world. The Neo-Concretes emerged from Rio de Janeiro’s Grupo Frente. They rejected the pure rationalist approach of concrete art and embraced more phenomenological art. The Neo-Concrete movement called for greater sensuality, color, and poetic feeling in concrete art, distinguishing itself from the more rigid approach of the original Concrete Art movement.[1] Ferreira Gullar inspired Neo-Concrete philosophy through his essay “Theory of the Non-Object” (1959) and wrote the “Neo-Concrete Manifesto” (1959) which outlines what Neo-Concrete art should be. Lygia Clark, Hélio Oiticica, and Lygia Pape were among the primary leaders of this movement.
