Great sense of rhythm! Goldenweiser and Ginzburg.

Rhythm is elusive. If you play just like a metronome it can sound just like a robot.
Rhythm should have a lusty sense of vitality, like a horse breathing, in a positive sense!

The best two pianists for rhythm that I have heard in recording are Rachmaninoff and Percy Grainger. The two have some genealogy in common: despite living half-way round the world from each other, they had related teachers (in Russia and Australia respectively)  brothers Pavel and Louis Pabst. Here is a two-piano piece by Rachmaninoff, dedicated to Goldenweiser, and performed by Goldenweiser with the astonishing pianist's pianist Grigory Ginzburg.
If you find your finger or toe tapping along, conducting in time with the music, you know that the performers can indeed say "I got rhythm!"

PS aficianados will find great interest in this interview with Ginzburg tucked away in the internet...

Nikolai Kapustin

I have been listening widely to this amazing Russian composer. Jazz influenced, he studied with Russian pedagogue Alexander Goldenweiser, and videos of Kapustin performing show that he amazing fluency and a biting rhythm. Over 100 opus numbers to his credit, hats off to him... Would love to know more about him, and how he survived all these years as a composer before being 'discovered' only recently.

His Concert Etude which I have been learning recently is tricky, but yields to practice.
There seems to be an inverse law, that pieces which sound difficult really do become easier the more you practice (Liszt, Kapustin), but pieces which sound easy (such as some Mozart and Bach) seem to become harder and harder!
