Cânticos Sertanejos, for flute, clarinet, and strings, is a work from 1907. It was recently (November 2010) played for the first time, at the Festival Villa-Lobos, conducted by its editor, Roberto Duarte. See this post at The Villa-Lobos Magazine for the first page of the score, and the story behind this work's re-discovery.
According to Charles Jacobs' "Villa-Lobos in His Centennial", 1987, Cânticos Sertanejos is also known as Phantasia Caracteristica, and there are in the Museu Villa-Lobos "...seventeen pages, eight in piano reduction, with occasional references to orchestration, the remainder in orchestral score but including rejected pages [sketches?]." (p. 255).
