Here is a lovely article about the human side of Villa-Lobos, written by Henri Leiser, a friend he made during his 1945 trip to the United States. I love these stories about Villa's special relationships with Rubinstein, Stokowski and Koussevitzky, and his love of children and vanilla ice cream. The anecdote about the Moment Symphony shows that Villa-Lobos could continue to think as a Parisian avant-gardiste even though by that time he had left behind the modernist style of the 1920s. Remember that John Cage's 4'33" wasn't conceived until 1947-48!
