That this recording was made at all is a testament to the incredible inner emotional strength and sheer musical intensity of the irreplaceable cellist, Jacquelyn Dupre who, while not yet diagnosed with multiple sclerosis, had been badly suffering its effects for some time. After six months of leaving the cello in the case during her convalescence, she suddenly pulled it out during a momentary period of strength and alacrity and made the recording. The recording thus serves as a testament to the power of the human spirit and Dupre's indomitable will. As well, the playing is superb. Dupre exhibited her characteristic intensity, superb line, and tone quality in a way that brought the pieces, particularly the Franck almost eerily to life. Barenboim, her husband, weeved a seemless accompaniment, proving himself even then a superb pianist. The music, too, is noteworthy. The Chopin sonata was one of the composer's rare forays into string music. WHile not an unqualified success, the piece still has much to recommend it. The Franck sonata, written for cello and transcribed for violin, is an utter masterpiece, particularly when in the hands of someone like Dupre who had the uncanny ability to manipulate human emotions with her instrument unlike almost any other. The sound quality of the recording is not quite up to modern standards -- it was recorded in the late 60's -- but this does not, in my opinion, detract from the greatness of the recording.
