This is true - except for the minor detail that Godowsky was actually the composer of those Etudes, but this is negligible.
Oh by the way - isn't Hamelin the Liszt and Alkan of today also?
Hamelin does not strike me as the audience pianist Liszt was, so I would say the Liszt of Today is closer to a Lang Lang or a Yevgeny Kissin.
Alkan was much more private, so again great Hamelin, who does perform in public quite often, is an ill comparison.
I actually think the most apt comparison to Hamelin today is with David Saperton, a fenomenal pianist who championed Godowsky's work and was a tad gun-shy when applying his incredible technique to the general repertoire. Hamelin surely has enjoyed a better public performance career and has had the benefit of a more developed recording culture than poor Mr. Saperton had access to.
