Real de Catorce, a blues and rock group from Mexico, was formed in 1985. Named after the mining town of Real de Catorce in San Luis Potosí, they gained immediate attention with their debut concert at Rockotitlán in Mexico City on December 12, 1985. Their early albums included Real de Catorce (1987) and Tiempos Obscuros (1988), featuring notable songs like "Azul" and "El ángel". Throughout the 1990s, they released several albums including Voces interiores (1992) and Contraley (1994). In 2006, vocalist and composer José Cruz Camargo suffered a respiratory failure during a concert due to complications from multiple sclerosis, leading to the band's eventual disbandment. The band resumed activities in 2009, releasing albums such as Una razón para vivir (2012) and Nación blues (2016).
