"Zamba de mi esperanza" is a cornerstone of Argentine folklore, composed by the Mendoza-born Luis Profili in the 1950s under the pseudonym Luis H. Morales . It was immortalized by the voice of Jorge Cafrune
Though written in the 1950s, the song gained massive popularity in the 1960s. It became a symbol of cultural identity and even resistance; during the Argentine military dictatorship, it was famously requested by an audience at the Cosquín Festival in 1978. Despite being "discouraged" or banned by authorities at the time, Jorge Cafrune performed it anyway, famously stating, "Although it is not in the authorized repertoire, if my people ask for it, I am going to sing it".
