Ernesto Lecuona (1896-1963), arguably the greatest Cuban musician of the twentieth century, produced some very fine classical Cuban music for piano, orchestra, opera and cinema.The "Andalucia" (from his Suite Espanola) is magnificent piano!
His "Siempre en mi corazon" (1942) got a Grammy nomination and was beat that year by "White Christmas".
"Maria la O" (1930) is from his famous zarzuela opera of that name.
P.S. Please excuse this little Summer diversion into my Cuban heritage!
