The album Saudade by Plínio Fernandes. There are lots of gems on this album. I especially enjoyed Aquarelle 2. Valseana and Aquarela Do Brasil, the first written by Sérgio Assad and the second arranged by him. Plínio Fernandes also performs the five preludes by Heitor Villa-Lobos. You might remember No.3 in A minor from my album Leaning Into the Night, where I performed it with a string section that was composed and arranged by the late Oscar Castro-Neves, who also produced the album.
Oscar told me that Villa-Lobos would do such wonderful things as hold up a piece of notation paper to the window of his Rio De Janeiro apartment and draw a line of the mountains, which he would then use for the melody.
