Festivals Simfonics Ibero-Americans
In 1929 Villa-Lobos was living in a flat on Place St.Michel in Paris. He was having a great time, hanging out with people like Cocteau, Diaghilev and Varese. He returned to Rio in August, but was back to Europe in October for this Festival of Ibero-American music in Barcelona. This notice in Mirador: setmanari de literatura, art i política includes a notice about a concert on October 25, 1929, that includes two of his greatest works, Amazonas and Choros #10.
