Born in the backlands of Alagoas, Hermeto Pascoal created one of the most singular bodies of work in Brazilian music. “O Menino de Olho D’Água” returns to his origins, revealing how childhood, nature and a deep attentiveness to the world shaped a unique musical language. Through memories, one of his final concerts and a conversation with the composer, the film unfolds as a luminous and quietly magical portrait of an artist who found the entire world to be a musical instrument.
