Throughout his life Sanchez traveled extensively and especially to the Caribbean islands where he became fascinated with the play of light and shadow on colored forms that became a dominant characteristic of his works. His early works of the 1950’s are stylized and figurative, depicting themes such as portraits of friends and models, views of New York City and tropical landscapes.
In the 1960’s his works became significantly more abstract, though always maintaining a strong sense of naturalism. It is during this decade that his work matured into an individual vision and when he began to develop his well-known paintings of houses and architectural themes. These architectural works stand out for their simplified forms where all superfluous details are eliminated. Stripped down to their essence these structures acquire universal meaning. Here he captured the effect of light on color making it vibrant. Despite the fact that his buildings are often devoid of visible inhabitants, they hold a strong living presence of their own. Throughout the 1970’s and 1980’s he further explored architectural themes by traveling to countries around the Mediterranean.
An artist with an independent voice and international acclaim, Sanchez has had over sixty solo exhibitions and has been included in numerous group shows in museums and galleries in the United States, Latin America and Europe. His art is well represented in private and public collections including over thirty museums such as the Blanton Museum of Art in Austin, the Museum of Modern Art in New York, the Metropolitan Museum in New York, the Museo de Arte Moderno in Bogotá, the National Gallery of Art in Washington D.C., the National Gallery of Australia in Canberra, and the Philadelphia Museum of Art in Philadelphia.
