Sviatoslav Richter plays Schumann Concerto in A minor Op. 54

i think mozzart was tchaikovsky's favorite..but i get your point

Schumann's music touches and affects me like nothing else can. For me, he is the one.

i agree !!

At 6:25 begins a passage that - to my opinion - strongly resembles for instance Rachmaninoff piano concertos style, especially the third one. But also perhaps Tchaikovsky, something from the russian school.

You picked up something obvious but not often mentioned... Schumann was Tchaikovsky's favorite! And Rachmaninoff used to say that "music has ended after Schumann and Tchaikovsky"! Strong musical/spiritual connections between these composers...

i strongly agree !
the first time i heard this concerto i thought it was by rachmaninoff, i never thought it was a work by schumann!

Well, you shouldn't really change the tempo of any piece anyways, there's a reason why it's marked a certain tempo, because the composer wanted it that way, that's how you play his/her work. If you don't follow that tempo, then you're not playing the piece, now you're making up something else...

As good as it gets.

it's not his interpretation that gives it a clonky sound. it's the recording. this was recorded in 1958, before the dawn of effective microphone techniques. and argerich is a fantastic pianist. but really, richter is one of my favorite pianists, and to say that the inability of a recording engineer to do an effective job makes him any less brilliant of an interpreter is downright foolish..
