Sorry, this is not even remotely the best, nor even Horowitz's best, Kreisleriana. The pianist was apparently even more nervous that usual ("revved up" according to Carnegie Hall's manager) before this concert. There's all sorts of scrambling during Kreisleriana's opening movement, which he doesn't come close to getting right. Even Harold Schonberg, who was generally positive toward Horowitz, panned the performance in his NYT review.
Of course, what this concert is most known for is not the Schumann, but the middle movement of Rachmaninoff's Second Sonata where the string snaps, bringing the concert to a temporary halt.
Horowitz repeated this program more successfully that December 1st in Philadelphia and again at Carnegie on December 15.
