Thanks for that David, glad you enjoyed them. For sure these pieces are far more than didactical.
Yes Bartok could be impressionist with the best of them, though he never has the cushy sound of a Debussy or Ravel.
It's always more angular, earthy, strange, dark, and personal.
I don't link the Bear Dance to Ravel's toccata. That latter one is far harder and more complicated. It's just that repeated notes are always a bicth to me
I don't know a Bartok 'Song of the Wanderer'. Yes it could be the one called 'Wandering'. Too long ago to tell
