The second movement of Ravel’s Piano Concerto in G, performed by Leonard Bernstein and accompanied by the Orchestre National de France:

 

I have never been a tremendous aficionado of Bernstein’s piano performances – a great (if variable) composer and conductor, he simply spread himself too thin to have made himself one of the greats. But this is a superb performance, very well conducted from the keyboard.

It is also interesting to see Bernstein (partly through necessity) adopt the pre-Liszt piano/orchestra configuration.
