This is a superbly written and engrossing variation set, in the manner of Bach and Beethoven, although I am certain that Hersch would forgive me for suggesting that he is not quite in those ranks. Nevertheless, the thoughtfulness and scope of drama here is impressive. There is never any sense that Hersch is merely filling out; all of the music counts for something. It is astonishing to read that he wrote this music in five days. This is a work that should get a wider audience, and the attention of more pianists.
