Although not a connoisseur but, neverthless, appreciative of fine classical music, I believe this performance by Martha Argerich to be, without doubt, the most exceptional I have heard and is comparable with any top virtuoso. It is no wonder that this highly talented lady has achieved so much. Considering that this recording was originally made over 45 years ago, I personally cannot fault the sound quality and, to me, it is just as if I were listening to a live broadcast by this magnificent pianist. Close your eyes, and it is easy to visualise a beautiful young lady in her mid-twenties, with raven-coloured hair, seated at the piano in a dress with white spots (as depicted on the sleeve) flawlessly producing this wonderful sound. The musical attributes of this lady are beyond description and I imagine that all of her performances were, and still are, of such excellent quality.
