HAVANA (AP) — Pablo Milanés, the Latin Grammy-winning balladeer who helped found Cuba’s “nueva trova” movement and toured the world as a cultural ambassador for Fidel Castro’s revolution, has died in Spain, where he had been under treatment for blood cancer. He was 79.

One of the most internationally famous Cuban singer-songwriters, he recorded dozens of albums and hits like “Yolanda,” “Yo Me Quedo” (I’m Staying) and “Amo Esta Isla” (I Love This Island) during a career that lasted more than five decades.

“The culture in Cuba is in mourning for the death of Pablo Milanes,” Cuban Prime Minister Manuel Marrero Cruz tweeted Monday night.

Milanés’ representatives issued a statement saying he had died early Tuesday in Madrid.

Pablo Milanés Arias (24 February 1943 – 22 November 2022) was a Cuban guitar player and singer. He was one of the founders of the Cuban nueva trova, along with Silvio Rodríguez and Noel Nicola. His music, originating in the Trova, Son and other traditional styles of early 20th Century Cuban music, set him apart from the style of Silvio Rodríguez.

Pablo Milanés, widely known as Pablito, moved with his family from Bayamo to Havana in 1950. He studied in the Conservatorio Municipal de La Habana, at the time the most prestigious musical school in the country. His first public performance was in 1956. By age 15, he was active in “bohemian” musical circles in Havana, associated with the so-called “filin” musicians.
