Written for orchestra in Rio in 1926, Choros #06 is dedicated to Arminda Neves d'Almeida.
Prof. Tarasti calls this work Villa-Lobos's Pastoral Symphony: "...it is by nature a lyrical work." He quotes Villa-Lobos:
"...the atmosphere of the work relects a sort of impression of the deserts of Northeastern Brazil: the climate, colors, temperature, light, birdsong, the fragrance of the capim grass blending with the capoeiras and all the elements of nature in a desert." Tarasti (1995), p. 109

This score should be available in most larger academic libraries, or through Interlibrary Loan from your local library.
For many years we were without a commercial recording of Choros #06, but things are much better now.
The ASV disc of the first seven Choros, Adrian Leaper conducting the Orquestra Filarmonica De Gran Canaria, contains a fine version of Choros #06.
But my first recommendation is the new disc from BIS, the first in a projected series of the complete Choros, with John Neschling conducting the Orquestra Sinfónica do Estado de São Paulo - OSESP.

The premiere performance of the work was on July 18, 1942, at the Teatro Municipal in Rio, with Villa-Lobos conducting the Orquestra do Teatro Municipal.
Lots of interest in this work lately: there are fifteen performances listed as of May 2010.
