The Best Piano Works of the 20th Century

Robert Greenberg, music historian and educator, has a course: The 23 Greatest Solo Piano Works. His choices from the 21st century are:

1. Debussy— “The Sunken Cathedral”
2. Debussy— Préludes, Book One
3. Albéniz—Iberia
4. Ravel—Valses nobles et sentimentales
5. Scriabin—Piano Sonata No. 5
6. Rachmaninoff—Etudes-tableaux
7. Prokofiev—Piano Sonata No. 7
8. Copland—Piano Variations

I have some listening to do!

Ligeti - Etudes
The last one might miss the 20th century (2001) but I always found these very enjoyable. I just realized I don’t have the third book :(

Excellent list as above.  Happy Listening!

Gotta have Rachmaninov's Paganini Rhapsody

I am going to mention 3 works I did not see above that I think have to be on this list.  First, the Shostakovich piano quintet and his piano trio number 2.   I would also add the Prokofiev Concerto #3.    A couple more pieces that I would not necessarily call great works, but works that I perceive to be under appreciated.  Those would be the Copland piano concerto, and Symphony no. 3 by Rued Langaard (you either like Langaard or you don't).  

I'd love to see @devilboy, @schubert, @frogman, and @learsfool weigh in on this thread.  Especially with respect to hidden gems that beg for more play time.
