The two hundred and sixty-fourth classical recording: #379 Mily Alekseyevich Balakirev - Islamey
Short, frantic and powerful. I saw this mentioned as one of the most difficult piano pieces to play and while I am not in the best place to judge this, I can understand why it would be from the pace, the frantic movement and changes. It sounds powerful, that strength of sound stretching through as a feat of brilliance. Short, but amazing just to listen to.
