Many excellent recommendations. It's sacrilegious to music (at least in my opinion), to not include Beethoven's 9th Symphony, which is The King of Symphonies. That Beethoven was deaf while composing a good majority of the 9th only adds to the luster.

I would also add in Beethoven's Piano Sonata's and String Quartets.

Bach's Solo Cello Suites.

When I have time (sometime in the next decade ) I will respond in more detail. Even actual recordings I prefer.
