Luis Kalaff was one of the godfathers of merengue in the Dominican Republic.  His sound took elements of the rural, accordion-based merengue típico and combined it with the style forged by the saxophone-led, big band merengue that came into style during the years of its efflorescence under dictator Rafael Trujillo, who essentially made the style into the semi-official national genre by imposing his taste on the country’s elites (he was from the Cibao region where merengue got its start).
