A portrayal of Joaquín Díaz, one of the most important Spanish figures in the musical, ethnographic, and cultural terrains, although his broad work is often unknown in its full extent. Commonly referred to as ‘the Spanish Pete Seeger’, the film rediscovers this precursor of the folk movement in Spain who in the 1960s also sang in Basque, Catalan, Galician or Asturian (languages banned under Franco’s dictatorship). When Joaquín was at the top of his career, he chose to retire from public life and moved to a small medieval village where he continues to work tirelessly in the ethnographic center he created, recovering folklore, past songs, and memory that would have certainly disappeared had it not been for his effort. Relevant musicians, writers, and scholars speak about his legacy and influence. Joaquín himself reflects on his own work and on society itself.
