Los Panchos

Los Panchos are a Latin trío romántico formed in New York City in 1944 by Chucho Navarro, Alfredo Gil and Hernando Avilés. The trio became one of the leading exponents of the bolero and the romantic ballad in Latin America. Its current members are Chucho Navarro Jr., Eduardo Beristian and Misael Reyes.
A characteristic instrument of Los Panchos and other Mexican tríos románticos since the 1950s is the requinto guitar, which is smaller and tuned higher than a standard guitar and was popularized by Alfredo Gil. Requinto solos found in many bolero recordings by Los Panchos.
