Your friend certainly had a way with Bartok, capturing his brittle nervous energy admirably.
The technique is a little shaky at times but I assume he was not so young anymore, so that
can be forgiven.
The Bartok pieces are from books 5 and 6 of Mikrokosmos.
Book 5: Burlesque Rustique, Quartes, and Cornemuse
Book 6: The Six Dances in Bulgarian rhythm, in the strange order 4,5,2,3,1,6
Though I know a goodly chunk of Villa-Lobos' piano music, these pieces don't ring a bell to me.
In fact I rather doubt these are by Villa-Lobos, they sound not at all like him. The first
could have been Ginastera, but I'm lost about the rest. Sounds more like French
to me, I seem to hear some references to French songs like the Marsellaise. If you find out
what this is,'d love to know. Interesting and very individual playing again.
Great idea to make a CD ! Sorry I could not help with the (supposed) Villa-Lobos items.
Thank you, Chris, for your so rapid and competent answer ! I knew you couldn't ignore the Bartok's pieces, being yourself another fan/specialist. Well, Francis was only 63, and we expected to have him many more years, but he got a sudden brain attack, the type of thing any of us may get whenever... He had a beautiful piano sound. As you noted, his technique was sometimes loose, partly because of some osteoarthritis that bothered him sometimes...
You're right, there are not only the Marseillaise, but other traditional French popular songs quoted in the second set of pieces. However, I've just read on the Internet that Villa-Lobos had many relations with France. He apparently made a long stay in 1923-1924 in Paris, and came back several times afterward. So he may have included these citations as a kind of hommage to French culture ? Anyway, he wrote about 1000 opus numbers, so this is not easy to screen all this material...
