The orchestra was founded on 1 May 1978, Labor Day in Salvaleón de Higuey, a town on the edge of the eastern part of the Dominican Republic.

An important start for the brothers was being hired by a teacher, Chiquitín Payan, to enliven activities at Casa de Campo, a Resort in La Romana, a town in their country.

Hits such as "Otra Vez", "Fuera de Serie" and "Insuperables" made the band one of the most listened to musicians in the Dominican Republic.

Songs such as "Rubia de Fuego", "Ingrata", "Mi Tonto Amor", "Bomba", "Cumandé", "Loquito Por Ti", "Dime", "Esa Morena", "Bríndame Una Copa", "Desde Que la Ví", "Mil Horas" and "Pecadora" kept the band under the spotlight.

Together with "The Owner of Swing", the theme "A day in New York" became quite a musical event, and the same happened with "kleptomaniac", "Video Clip", "Candy", "Hot Women", "oleyl", "Oh, how lonely" and "Woman banned".

This recording session was entirely made in the Dominican Republic, and for this the Rosary Agency gave the services of the best technicians, composers, musicians and arrangers of their country.

With the album "Aura" the band confirmed their qualities and commitments to the merengue genre, blending the typical style with other musical elements and innovative colors in wearing.
