Curious as to the opinions circulating on something that inevitably causes sensitive issues:
Some performers add effects, for lack of a better word, to the Chopin scherzi and i think at times they are justified. Pletnev in particular stands out as doing it correctly to me, the end of the 1st Scherzo is terrifying, but he achieves the effect by amplifying the bass. I'm not exactly sure what he does, but the Carnegie hall performance is incredible and it's complemented by that approach. He does something similar in the middle climax of the 2nd Scherzo.
Samson Francois takes more liberties, but i don't really think they always work. Particularly the 3rd Scherzo. But he belongs to a different tradition altogether.
And then there's Horowitz. I don't think the octaves are necessary at the end of the 1st.
Opinions?
