The Difference between good and GREAT in classical music is an online article comparing two recordings of Shostakovich's Fourth Symphony. This is one truly great listening experience, because the given sound samples can be paused, then you can listen to a short section on the other recording (good vs. GREAT!) and then re-start the paused recording.
A fabulous instant-listening educational experience for all musicians.
Take a listen:
The lyricism and emotive power of the Chicago Symphony interpretation is immediately apparent. And check out the complexity of the characters in the woodwinds!
Just love this.
