Adelaida Diestro Rega, known as Aida Diestro, was a distinguished pianist, arranger, and director of the D’Aida Quartet. She was born on December 21, 1924, in Havana. She began her musical studies as a student of her father and later enrolled and completed them at a private conservatory.

She served as choir director at the church where her father, a Presbyterian pastor, officiated. She attended the gatherings held at Enrique González Mántici’s home, seeking to broaden her knowledge.

He began his professional career as a repertoire pianist at the radio station Mil Diez, where he met important figures in Cuban music such as César Portillo de la Luz, José Antonio Méndez, Tania Castellanos, Luis Yáñez, and Adolfo Guzmán.

In 1952, she founded a vocal quartet, which she named after herself, D’Aida. Initially, it consisted of Elena Burke, Omara and Haydée Portuondo, and Moraima Secada. They made their debut on the television program El show del mediodía.

He toured with the quartet in countries such as Venezuela, Mexico, Argentina, Japan, Poland, the United States, France, Germany, Russia, Poland, Czechoslovakia, Hungary, and others.

With the quartet, she performed twice nightly at Tropicana (4504 72nd Street, Marianao, Havana), and at the Patio del Hotel Habana Libre (corner of 23rd Street, Vedado, Plaza de la Revolución, Havana). In the early 1970s, Aida added an orchestra with batá drums to the group.

Aida Diestro, or as she was known, “La Gorda de Oro,” made Las D’Aida one of the essential groups of Cuban feeling and music, despite the numerous changes in its members, since its director prepared the singers’ voices very well and they launched themselves as soloists.

Her accolades as a director also include the creation of the first male quartet, which included Luis Téllez, Simón Roberto, José Olmos, and Gilberto Vaillan.

Adelaida Diestro Rega, died on October 28, 1973.

In January 2011, a posthumous tribute concert was held in Camagüey for this prestigious Cuban musician. It featured performances by artists such as Simón Roberto, Gipsy Casals, Papito García, Idalgiza, and Gilberto López, among others.
