Du Pre's cello playing is magnificent here, and it is indeed a great pity that the music world has lost a superb artist at such an early point of her career!
To my ears the work that fared best, and is more musically satisfying, is the Haydn concerto. The nearly flawless cello playing and the English Chamber Orchestra's uncanny virtuosity under the direction of Barenboim add up to much more than the sum of the parts -- a remarkable musical event, well recorded for posterity!!!
Du Pre's masterly command of the cello and beauty of sound, however is recorded with excessive presence in the Dvorak concerto. The balance between the lovely cello sound and the Chicago Symphony is artificially slanted much too much towards the cello microphone, hence the resultant effect is one of a huge cello, albeit beautifully played, accompanied by a tiny sounding orchestra, way far in the distant background. This concerto is in reality a symphony for cello and orchestra containing a rich tapestry of interweaving inner voices as well as important musical material that needs to be heard with equally balanced prominence. The moments where the melodic material played by various instruments in the orchestra should be heard, are very poorly balanced, rendering them nearly completely obliterated by the cello's accompanying pyrotechnics. I can in no way, nor do I wish to, fault Du Pre's playing here - it is simply angelic! For that reason as well as the superb Haydn, I still recommend that every aspiring cellist or cello aficionado purchase this CD.
To me, the most musically satisfying CD of the Dvorak that I have heard so far is the 1969 Rostropovich/Karajan/Berlin Philharmonic Deutsche Grammophon recording.
