This amazing guitarist Jesús Castro Balbi is not to be mistaken for his son Jesús Castro Balbi (!) who is a cellist and seems to be more famous.

Agustín Barrios Mangoré was a Paraguayan virtuoso guitarist and composer. This masterpiece is one of his contributions to the classical guitar repertory.
