Quite simply, I would rate Oistrach's performance of the Brahms concerto here as the very best I have heard. A wonderfully atmospheric reading, perfectly paced, full of grandeur and warmth. The Tchaikovsky concerto is similarly a splendid performance. These are great documents from the past, worthy of any collection, although because of their age, the sound is a little mushy. But this is a minor criticism: it almost adds to the sense of a truly great occasion from the past.
The sound quality is not an issue on the Bach concertos and the Beethoven romances. Period performance purists may baulk at the sound of modern instruments in Bach playing, but Oistrach's lightness of touch manages to convince here so very well. The characteristic Oistrach warmth is clear as is a brilliant mix of the playful and serious. These are gorgeous performances, which for me are as great as they were when I first got hooked in the early seventies. Igor Oistrach joins his father in the Bach double violin concerto; surely the slow movement in particular is one of the greatest performances of all time.
And the Beethoven is simply beautiful. Lovely romantic miniatures performed to perfection by a musician clearly at the height of his powers.
