Israel López Valdés, better known as Cachao, was a Cuban double bassist and composer. Cachao is widely known as the co-creator of the mambo and a master of the descarga. Throughout his career he also performed and recorded in a variety of music styles ranging from classical music to salsa. An exile in the United States since the 1960s, he only achieved international fame following a career revival in the 1990s.
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.
