Born into a family of musicians in Havana, Cachao and his older brother Orestes were the driving force behind one of Cuba's most prolific charangas, Arcaño y sus Maravillas. As members of the Maravillas, Cachao and Orestes pioneered a new form of ballroom music derived from the danzón, the danzón-mambo, which subsequently developed into an international genre, mambo. In the 1950s, Cachao became famous for popularizing improvised jam sessions known as descargas. He emigrated to Spain in 1962, and moved to the United States in 1963, starting a career as a session and live musician for a variety of bands in New York during the rise of boogaloo, and later, salsa.
