Los Panchos, originally known as Trio Los Panchos, are a legendary trío romántico formed in New York City in 1944 by Mexican musicians Alfredo Gil and Chucho Navarro, and Puerto Rican musician Hernando Avilés. The trio became one of the leading exporters of the bolero and romantic ballad in Latin America, selling hundreds of millions of records since their creation in the mid-1940s. Known for their interpretations of classic folk songs such as "Besame Mucho" and "Quizás, Quizás, Quizás," Los Panchos enjoyed US chart success in 1964 with the album "Amor" featuring Eydie Gormé, followed by three more albums together. Over their seven-decade career, they sold out concerts globally and appeared in more than 50 films, cementing their status as one of the top musical trios and most influential Latin American artists of all time. A characteristic instrument of Los Panchos and other Mexican tríos románticos is the requinto guitar, which is smaller and tuned higher than a standard guitar, often featured in their recordings.
