Query: Unsurpassed Musically and Sonically

There are plenty of enthusiastic reviews that attest to the quality of this performance, so I can only add, emphatically, that this is the greatest recorded performance of one of two of the greatest pieces by one of the greatest Modern composers. That being said, CD buyers are often wary of the sound quality of early stereo recordings remastered on CD. To them I would say that this is also one of the very best sounding CDs you will ever own of any music, recorded in digital or analog. Absolutely full, rich and clear sound, simply beautiful to the ear. One of the great classical recordings ever made.
