Caifanes is a Spanish-language rock (Rock en Español) band from Mexico City formed in 1987. They achieved fame throughout the late 1980s and early 1990s. The original lineup consisted of Saúl Hernández (vocals & guitar), Alejandro Marcovich (lead guitar) Sabo Romo (bass guitar), Alfonso André (drums) and Diego Herrera (keyboards and saxophone). Caifanes’ style can be described as a hybrid of British new wave, progressive rock, and Latin percussion underscored by deep, somber, and Latin American-Mexican-Spanish influenced lyrics and the vocal style of Saúl Hernández. Members of Caifanes have cited King Crimson as a major influence.

The name Caifanes is derived from 1940s Mexican Pachuco (zoot suiter) slang "Cai fan". Its equivalent in English would be something like “cool dude.” The word has also been used to describe the proverbial Mexican Pachuco, delinquent, or outsider.
