Yes, indeed, the English hornist of the New York Philharmonic is playing the Ravel Piano Concerto … on piano AND English horn.

I have no words!

From the YouTube page:

Double threat! Watch as New York Philharmonic English Horn Ryan Roberts performs Ravel’s Piano Concerto in G major as both soloists: piano and English Horn.

In Ryan’s words:

“Finally!! The English Hornist gets to choose the tempo. When Ravel was praised for the beauty of this melody, he responded, ‘That flowing phrase! How I worked over it bar by bar! It nearly killed me!’ I think oboists can relate to this sentiment.”

(I actually enjoy it a wee bit slower, but that’s just me and I am certainly not qualified to play in the NYPhil!)
