Singer. Called "The Queen of Bolero", she is remembered both as one of her country's premier vocalists and as an opponent of the Castro regime. Raised in Havana from early childhood, she apparently learned her art by singing along with popular music of the day. In her early teens she formed the duo 'Las Hermanitas Guillots' with her sister Ana Luisa and developed a popular following on Cuban radio. The pair broke up after Ana Luisa's 1940 marriage and Olga continued as a solo act through the World War II years; in 1945 she began headlining at major Havana nightclubs then in 1947 she traveled to New York where she cut her initial disc for Decca. A 1948 trip to Mexico established her as a star there and saw the first of her numerous movies, in most of which she played herself. Over the ensuing decades she would tour extensively in Latin America, the United States, the Far East, and, starting in 1958, Europe, singing only in Spanish and sharing the stage with Frank Sinatra, Edith Piaf, Sarah Vaughan, and others. Olga first sang what was to become her signature piece, "Mienteme" ("Lie to Me"), in 1953, and in 1954 used it on the first-ever gold record by a Cuban artist. A courteous but vocal opponent of the Castro regime, she left Cuba permanently in 1961 and after living in Venezuela divided her time between Mexico and Miami. In 1963 she received the Golden Palm award for bolero and in 1964 became the first Latin artist to sing at Carnegie Hall. Although she declared herself "semi-retired" after 1982, she continued performing for the rest of her life and made her last album, "Faltaba Yo", in 2007, the same year the Latin Grammys presented her with a Lifetime Achievement Award. At her death from heart disease, much of her large recorded legacy remained in print though her records continued to be banned in her native country.
