Cuco Valoy, born on January 6, 1937, in Manoguayabo, Santo Domingo, Dominican Republic, is a renowned singer, songwriter, and instrumentalist known for his contributions to various musical genres, including salsa, son montuno, merengue, guaracha, and bolero. Valoy's musical journey began in the late 1950s when he formed the son duo Los Ahijados with his brother Martín, achieving significant success and filling a cultural void left by the decline of Cuban music exports post-1959. Known for his versatile talent, Valoy played various instruments, including vocals, maracas, guitar, and percussion instruments like the tambora and bongos.

Valoy's career spanned several decades, from the 1970s to the 1990s, during which he transitioned from traditional son to salsa and merengue. He is also recognized for his role as a producer, working with pioneering musicians and promoting the Dominican variant of bolero known as bachata. Valoy's influence extended to radio, where he was the first disc jockey in the Dominican Republic to play bachata on air, under the pseudonym "El Suki Suki sabroson."

As a family man, Valoy is the father of Ramón Orlando, with whom he formed the band Los Virtuosos, later known as La Tribu. His song "Juliana" gained international recognition when covered by the group DLG, featuring Valoy's vocals. Throughout his career, Valoy released numerous albums and compilations, leaving a lasting legacy in the Dominican and international music scenes.
