A nice way to present the original Chopin Etudes (opus 10 only) and then the Godowsky versions, one by one.
In general I don’t like how he plays the Chop version, often too rigid & dry (though very fast), but the Godowsky Etudes are quite stunningly played.
The amazing thing here is that this guy isn’t even a pianist in the normal sense - as he’s doing a lot of other musical stuff as well.
