He visited the United States briefly in 1947 and became a Mexican citizen in 1956. His next appearance in the U.S. was in San Francisco for the New Music America festival in 1981. He traveled regularly in the following years and lived in the current Casa Estudio Conlon Nancarrow (designed by Juan O’Gorman) at Las Águilas, Mexico City, until his death at 84. He was friends with some Mexican composers but was largely unknown in the local music establishment.
