We often speak of certain Brazilian composers suffering in the shadow of Heitor Villa-Lobos. After all, he was the one who possessed not only musical genius, but also the ability to attract attention.
He was, in many ways, bigger than life, which made it a struggle for other very able composers to be seen and heard. These others included Camargo Guarnieri, Franciso Mignone and Claudio Santoro. The music of these composers is still struggling to be heard outside of Brazil.
