La Afinación del Diablo plot
On June 19 of this year, Paraguayan guitarist Efrén 'Kamba'í' Echeverría passed away. His personal musical style, with a different guitar tuning and a special playing technique, is the subject of this film. With our own ears we hear how two guitars seem to sound at the same time when he plays. What is his secret? And does he take that with him to his grave or does he pass it on to the next generation? It is rumored that he learned his technique from Peloncho, a sinister man many have heard of but no one has ever met. Peloncho would have sold his soul to the devil.
