El Cieguito de Nagua, whose real name is Bartolo Alvarado, is a cherished figure in the realm of traditional Dominican music. Born in the town of Nagua in the Dominican Republic, he earned the moniker "El Cieguito" (The Blind Man) due to his visual impairment. Despite his disability, Alvarado became one of the most recognized interpreters of merengue típico, also known as perico ripiao, which is the oldest style of merengue deeply rooted in Dominican culture. He mastered the accordion, which is the leading instrument in this genre, and his music is characterized by its rural, accordion-based ensemble, combining African and Spanish influences.

Throughout his career, El Cieguito de Nagua recorded a substantial body of work that has contributed significantly to the preservation and enjoyment of merengue típico. His albums like "15 Exitos" and "Aprovechate" feature a collection of hits that have resonated with audiences, both within the Dominican Republic and among the broader Latino community. His songs often tell stories of rural life, love, and humor, and his distinctive voice and skillful accordion playing continue to inspire a sense of national pride and nostalgia. Despite being less in the public eye in comparison to mainstream merengue artists, El Cieguito de Nagua is respected for his dedication to the traditional sounds of the Dominican musical heritage and remains a beloved figure in his genre.
