"Heifetz's recorded legacy is particularly rewarding for reasons other than the simple fact that he was a great violinist. He obviously liked to get away from standard repertoire and explore the byways of violin literature. He gave much attention to music of his own time—nothing too 'modern', mark you; and he clearly enjoyed the experience of playing chamber works with other great artists....
This charmingly slight early work [Beethoven's Serenade] is played with much affection and warmth, as is the even less substantial, even rather empty Spohr concerto...Spohr's Double Quartet, well recorded in 1968, has much more character than the concerto. Here Heifetz very much blends in with his colleagues, and if he is in charge of the extremely alive, superbly played performance it is not apparent in the final result."
