Arrau could be an erratic Chopin performer - even his greatest admirers, like myself, do not find so much to admire in his recordings of the Chopin concertos. His recording of the Nocturnes, however, is astounding. They take you to places you never thought existed; in a strange way, they make you believe in a better world, a world of harmony, beauty, simplicity and perfection. Just listen to the posthumous Nocturne in C-minor, one of the simplest and 'easiest' pieces here, that we now know is a very late (and not an adolescent) work and the beauty takes your breath away. Listening to Garrick Ohlsson's account immediately afterwards, fine playing though it is, brings you back to earth. Had Arrau recorded nothing else but these Nocturnes (and the Impromptus generously included in these CDs) he would be among the immortals of the piano.
