Arthur Rubinstein Chopin recordings of the Nocturnes, from 1936-7, and the long series of Mazurkas, set down in 1938-9, show a balance, almost unique, between spontaneous feeling and the mature consideration which these readings embody. Rubinstein"s communicative fire is always apparent, reflected in the rich, always personal tone he produces in the Mazurkas, capable of a vast diversity of nuance.
