This was posted to YT several years ago so it may not be new to some of you, but I just stumbled on it. It's an interesting dissection of the Beatles music from the perspective of a classical musician and composer. It's more than your typical "look how they referenced Bach" or whatever and goes much deeper than most such programs. The presenter basically credits the Beatles with saving traditional classical music following the avant-garde experimentations of the 50s and 60s.

I found it to be a thoughtful and entertaining use of 48+ minutes and highly recommend it to all the music nerds who inhabit our little corner of the interwebs.
