I'm doing a research (quasi dissertation) for a class, and would need specific information on latin american classical composers, especially of those that were active during the 19th and 20th century.
Marion Verhaalen has a publication about our Brazilian composer M. Camargo Guarnieri, an important figure of the nationalist school of composition. I also have shared some articles here about him and VIlla-Lobos.
There has been a recent interest among so-called "Early Music" performers in post colonial music in Latin America and in fact there are a number of recordings as a result. Might I suggest if you are studying this period a bit of independent musical analysis would be appropriate. I offer the following recordings as a point of departure:
Jerusalem: Matins for the Virgin of Guadalupe, 1764
Ignacio Jerusalem y Stella (Performer), Joseph Jennings (Performer), Chanticleer (Performer)
