It's hard to decipher all the text of the story by Glenn Dillard Gunn, but what I can make out is very interesting, in a gossipy way. Gunn visited Villa-Lobos in Rio in 1940, during Stokowski's visit. Meeting Villa-Lobos at his office, he noticed the composer was uncommunicative and edgy.
"Then I learned why he was nervous. He wanted to get to the Teatro Municipale, where Stokowski was rehearsing his new piano concerto. The pianist, a statuesque blonde named Tagliaferro, did not please him. Nor, seemingly, did Stokowski."
