I have become obsessed with this rondo by Francois Couperin after coming across an incredible video performance of if by Grigory Sokolov.
This page details some of history of this piece.
You can hear a brief sample of Alexandre Tharaud's interpretation of the piece via amazon here. Tharaud's interpretation is quite different in terms of articulation and sound than Sokolov's, which is brilliant and "pingy". (I personally prefer Sokolov's performance, which you can purchase via amazon.)
For a pianist, the technical challenge arises not from the fingerwork of either hand, which is relatively simple, but from the placement of the hands over one another. Since this piece was written for a two manual instrument, playing it on the piano means that one hand is constantly above the other, often with notes being played at the same time...which can be a little confusing. Then of course there is the challenge of keeping the various lines distinct, clean repeated notes, and all that stuff. Check out this home video(?) of the piece on a two-manual harpsichord.
I'm going to try to video tape own attempt soon enough :-)
