772 p., George Gershwin introduced Afro Cuban Music in America in 1926. Xavier Cugat during the 1930's introduced The Rumba dance. Three great innovations based on Cuban music hit the USA after World War II: the first was Cubop, the latest Latin jazz fusion. The rumbustious conguero Chano Pozo was also important, for he introduced jazz musicians to basic Cuban rhythms. Cuban jazz has continued to be a significant influence. The mambo first entered the United States around 1950, though ideas had been developing in Cuba and Mexico City for some time.
