Pablo Bruna
Pablo Bruna was a Spanish composer and organist notable for his blindness, which resulted in his being known as “El ciego de Daroca”. It is not known how Bruna received his musical training, but in 1631 he was appointed organist of the collegiate church of St. María in his hometown of Daroca, later rising to choirmaster in 1674. He remained there until his death in 1679.
