Again about Nadia Boulanger, in another letter to Florica Musicescu (June 24, 1936):
Miss Boulanger gets more and more admirable! A couple of days ago she conducted the Philharmonic Orchestra from Paris in an extraordinary programme. I tell you honestly that I burned with indignation at the thought of all conductors who have the possibility of leading such grand works, in such a grand way, and yet they don’t. The limit to the narrow repertoire after Bach and up to Debussy. Nothing before Bach, and nothing of our times.
