"Oistrakh's playing was not so much marked by brilliance, but by richness, lyricism, roundness of tone; the unbelievable sharp and clear contact between string and bow, his ability to lengthen the bow stroke on even the shortest notes without the slightest tension, his beautifully fleshy, supple left hand capable of producing glorious vibrato together with an infinite variety of shades."
