Oistrakh was peerless, a real poet of the violin, and his performances here are always fascinating and beautiful to listen to. Time and again here he turns a phrase in a way that seems just right, and some moments are breath-taking. He is accompanied by his long-time sonata partner Lev Oborin. Oborin is always competent and, as you listen, there is little or nothing to complain about, but if you compare him with, say, Schneiderhahn's partner in the same sonatas (Kempff) or Francescatti's (Casadesus), you realise that there is more in the music than Oborin can find. So it is a rather unequal partnership. I must stress, however, that Oborin does not let the side down. Oistrakh's mastery comes across untrammelled, and it is just a pity that he is not playing with someone of comparable stature.
