Singer and actress Rosario began her career in the mid- to late '70s; billing herself then as Rosario Rios, she recorded ¿Que Querrá Decir Esto? (1976) for CBS and acted in the film Al Fin Solos, Pero... (1977). Not much came of her efforts during this period, and her career went cold until 1984. Minor success was sustained through Muchas Flores (2001), a grand comeback that rejuvenated Rosario's career as an actress, in addition to her recording career. Her efforts were recognized by the Latin Grammy voters, who regularly nominated her for Best Pop Vocal Album, Female: she won in 2002 and 2004 for Muchas Flores and De Mil Colores, respectively. ~ Jason Birchmeier
