Oh sorry, it's just Leonard Bernstein condensing his musical (and general) philosophy in a lecture series at Harvard, without insufferable thumbnails. Probably of no interest....
I acquired the entire Norton lecture series on LP decades ago. Listening now illustrates how much useful information has fallen through the cracks for Conductors, composers and musicians in general. Instead of “The unanswered question”, maybe a more modern title would be “The forgotten answer”.
