I meant to listen to this in December but Christmas was...a very unholiday-esque and crazy time. This was free on Audible at the time and I had to try it. If it were longer (as it should have been!), I'd have bought it in a heartbeat. Professor Robert Greenberg was so easy to listen to and tied together "not" Gregorian chants, Handel's Messiah, and Tchaikovsky's Sugar Plum Fairy played on a celesta. The musical excerpts were wonderful and he used them well.
Greenberg includes, as a treat, Sir Peter Maxwell Davies' Country Dance from Eight Songs for a Mad King, which begins with a...disturbed version of Handel's "Comfort Thee My People". It's...something I've never heard before. If you're interested to hear more, here are a couple videos I've found about it.
Video explaining a bit about what's happening musically. (I highly recommend this!)
I may have to suddenly learn more about music.
