Soon after, she joined popular music groups like the Moncho Usera orchestra, and then she released her first album, which contained the hit Tierra Rica (Rich Earth).
During the 1970s, Carmita became a part of the Disco Music movement in her country, and had the number one hit La Generacion De Hoy (Today's Generation), produced by Alfred D. Herger, which was followed by La Vida En Rosa (Life In Pink), a song which was later a hit in English too, Grace Jones performing the English version.
In September 1990 she debuted as a stage actress in the San Juan premiere production of Rodolfo Santana's "Baño de Damas", with an all-star cast that included Gladys Rodriguez, Giselle Blondet, Marisol Calero, and Johanna Rosaly.
In February 1991 she returned to the stage as Sister Mary Hubert (Sor María José) in the San Juan premiere production of Dan Goggins' musical comedy "Sor-Presas" (Nunsense).
As it turned out, there was a reason for her winding down the number of public appearances each year: In 2002, she announced during an interview with Vea that she had been diagnosed with cancer in 1985.
