This performance of the crowning etude of the set is extremely good. Of course, over 11 years one can get new ideas and see new things in music, so maybe a performance nowadays would be in some ways different?
By the way, I think that in the last few days I've finally worked adequately through the mania induced by Swedish cabin fever, which usually peaks near the end of February, so I might not be as active here as much for the next few months . . . watch out though for January, and especially February, of 2016! . . . LOL
Now I am going on to hear the No. 5 etude.
Thanks for sharing these links!
