María de los Ángeles de las Heras Ortiz, better known as Rocío Dúrcal, was a Spanish singer and actress. Her career, which spanned more than four decades, began in the 1960s, when she established herself as an actress and singer thanks to the musical films she starred in. Later, she focused exclusively on her musical career, performing canción melódica, boleros, and rancheras, which led her to be considered one of the best Spanish-language singers of all time.
