Since the 30s, the rise of big bands in Cuba was an indisputable fact, and his presence on the island had been in the previous decade. So little haphazard and more as a logical development of the spirit of Jazz, Cuban gangs imposed a contract on the island, from Northern America, as those incorporated into their repertoire Cuban music, especially danzón, boleros, canciones, as formula for the exploitation of commercial music. At this time we found the banda of the Castro brothers, the Curvelo the Palau, Don Aspiazu Havana Casino and also the Siboney, Alfredo Brito, the Lecuona Cuban Boys, Armando Oréfiche, the Casino de la Playa, the Armando Romeu , Riverside, among others. Parallel to the indisputable presence of

jazz in Cuba, there is the phenomenon of expansion of Cuban music in the entertainment capital of the moment: Madrid, Paris, Mexico are among the capital welcomed ardent enthusiasm of Cuban music. This increases the exchange between artists, which produces an "invasion" of these orchestras Cuban capital.

Cuba flourished in the music industry with the advent of radio and competition between broadcasters and the entertainment industry. At the end of the 40s, is the feeling, a movement initiated by the various composers who intentionally left the influence of Italian music and Spanish and was an approach to jazz. Formed part of the group figures as Jose Antonio Mendez and Cesar Portillo de la Luz, who with other members of the movement reproduced of meetings to interpret jazz, which in this context given the Latin name of discharges, the current term and decade of 60 in New York. Figure of the whole or group based on the discharges were: The Black Alejandro Vivar, trumpeter, Tata Palau, tenor sax, Bebo Valdés, piano; Fernando Vivar, bass, and Barreto, on drums.

So were the conditions that arise in the same period the figure of Damaso Perez Prado and the mambo rhythm, characteristic fusion of jazz and Afro-Cuban. In the 50s, there was the magnificence of the Cuban music produced to date and this is confirmed also by the rise purchased at the tourist island, which in turn shapes the mass film, the musical that includes obviously jazz figures of world renown, such as Sarah Vaughan, Cab Calloway, June Cristy, Tony Bennett, Eartha Kitt, Xavier Cugat, Josephine Baker, Edith Piaf, among others.
