Gosh, I love this man! What a marverlous technique! I really like his approach to this piece - brilliant but also carefully measured and crystal clear, as well. Very suitable for Ravel. Such a big, wonderful tone!
Here is a link to the whole concert, during which he plays 'Gaspard' in its entirety. "Ondine" begins at 27'26". The timestamps are in the description, but this link will jump you to the beginning of "Ondine". And unlike the "Hamelin Plays Ravel's 'Gaspard de la Nuit'" video, this one has sound. Hope this helps! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rjEuggdLqec.html
