The records reflect business and artistic activities of Orquesta Típica Cubanakán, a Miami-based group founded in 1968. It cultivated a traditional Cuban genre, the danzón. The orchestra consisted of nine members: conductor and flutist Simon Hernandez Padrino; pianist Raquel Valladares; bassist Juan T. Sanchez; saxophonist L. Borrel; drummer M. Socarras; "guiro" player M. Garcia de la Vega; and vocalists Marta Escauriza and Guillermo Ramos. Other musicians also participated in the Orchestra during its history. The materials document the group's mandate of preserving Cuba's cultural musical traditions, and its involvement in social, festive, religious, and cultural events.

The bulk of materials consists of danzón music scores, both manuscript and published. The materials also include four scrapbooks illustrating the group's history through photographs, clippings, correspondence and business cards. The collection also includes programs, proclamations, a book with annotations and diplomas.

The papers document activities of Hortensia Montero (1909-1998), Cuban mezzosoprano and composer. Materials include photographs, autographed notes, programs, diplomas, clippings and music scores.
