In Youtube, there is a historical performance of this music by Richter and Borodin Quartet. The performers, especially Richter, are not self-asserting but are only letting their performance express what this class work is. Beautiful, faithful and classy. The 2nd movement is, in my view, one of the most beautiful musics in the history. This piece as well as his other musics tells what personality, most honest, faithful and earnest, he had. That must be the reason why there were so many composers learning from him, directly or indirectly, who have been named as Franckists.
I have played the 1st movement of this music twice. The first time was at a small concert for farewell to the graduates at the university orchestra. The pianist, a quiet girl majoring in music, has played it, I remember, as if she had become insane. The other chance to play it was when I came back in music around 50 years of age. The string players and the pianist were all good friends of mine. Another fond memory. I am still feeling thankful for them all giving me chances to feel this wonderful piece closer to myself.
This is an unforgettable music for me in multiple meanings.
