This is the first time I've heard this piece of Godowsky, and yes, the harmonies are definitely rich, a Godowsky hallmark. I believe you played it very convincingly. A very nice recording indeed! Plus you fulfilled your pledge by completing your part of the project! Many will appreciate that, I'm sure.
What I've always found is that if we have some favorite composers, inevitably we'll love many of their works, but others... not so much. Taking Godowsky as an example, some of his pieces in the Java Suite
are of incredible beauty, but others, despite the cleverness of Godowsky's creativity and depictions, leave me less enthused. I also believe that sometimes becomes a hurdle to doing complete sets, especially when one must learn pieces that don't excite nearly as much as some others therein. It takes self-discipline, objectivity, motivation and perseverance to overcome that hurdle. Clearly you jumped over it with No. 25.
even though I liked it when I first started learning it, I have now become so sick and tired of it
I can certainly relate to that! At the moment I've been preparing a Medtner piece which when played sounds ever so easy. But for numerous reasons the piece is a beast to play! If and once I record it (and hopefully keep my sanity), I know I'll be putting it behind me. But, similar to your perspective, I'll always be glad too that I learned it.
Again, thanks for presenting No. 25.
