Portrait of Camargo Guarnieri.

Camargo Guarnieri (conductor) had an important intelectual mentor: Mario de Andrade. In 1928, just after presenting two of his works ("Canção Sertaneja" and "Dança Brasileira"), Andrade invited him to be an often visitor of his house, where they discussed aesthetics, listened musical pieces, and exchanged books. Andrade not only became a very good friend of Guarnieri, as he also was responsible by promoting and explaining the composer's work for a broad audience through his articles in newspapers.
