Actress, Singer, Dancer. She is most remembered for her entertainment career from the late 1940s to the mid-1970s in the cabaret burlesque lifestyle of Buenos Aries, Argentina. Being labeled as one of the “first sex symbols of Argentina,” she was known for her beauty and sex appeal, thus often pictured in magazines. Born Nelida Mercedes Musso, not much is known about her childhood except that her father was Italian and her mother Spanish. Her career debuted with her marriage and business partnership with Julio Rivera Roca, a jazz pianist; she became a singer with his orchestra. Using her husband's surname, her stage name became La Roco, “The Rock.” In 1948, Luis Cesar Amadori, film director and owner of the historical theater of the city, Teatro Maipo, heard her singing jazz at the night club, Confiteria Richomond. Recognizing her raw talent and beauty he produced the show “Treato Maipo” and with that a star was born at the age of nineteen. A demanding audience would pay any price to see her show, hence the price of the front-row seats tripled. She quickly became a legend being photographed with well-known actors and singers of the age. She appeared on local TV shows and interviewed about everything from details of her personal life to her diet to maintain her figure. She was known for her figure in a time when there was no plastic surgery to correct faults. Her earlier stage clothes of the jazz singer were soon changed to scanty sequin-layered costumes, 3-inch high-heeled pumps, tall feathered headpieces in her brunette hair, and tights for her long legs. Photographs and more photographs were taken of her. A magazine would hit a sells record with her photograph plastered on the cover; this continued regularly until her retirement from the stage in the winter of 1974. Her last public performance in Buenos Aries was “La revista de ora”. Within a year, her health declined, which was caused by progressive arthritis and led to renal failure requiring daily dialysis treatments. Wheelchair-bounded, she first traveled to Cuba to a clinic without much results, and this followed with various other clinics and hospitals for the last two decades of her life. She did marry several times, but depending on the source, the name of the groom and the number of marriages did change: After Roca from 1949-1962, printed sources list Amalis Lacroze de Fortabat; from 1963 to 1969 vocalist, Aldo Perricone AKA Ricky Giuliano; a model, Alberto Persico; and Dr. Herman de Lafuente. Memorabilia such as an old magazine article with photograph of her with Persico can be purchased for $65 and a program from her theater days for $500. After a long history of health problems, she died of a heart attack at the French Hospital. She was called the “Venus of the Theater District.” Her successful career was founded on a natural beauty, basic raw talent in voice and dance, and outstanding publicity. In 1996 a plaque to honor her was place in the vicinity of the Maipo Theater, the scene of her greatest artistic shows.
