Horowitz out-did even himself at this concert. Sure, wow, wrong notes, even in the first couple measures. Who cares. You had better not. I noticed two exposed wrong notes in my first listen of this disc. It is by far the best CD set I own.
Toccata, Adagio and Fugue in C Major: Sure, wrong note. Grand. I'm not too large a fan of this piece, but, regardless, if you like Bach, you like Horowitz for this recording.
Fantasy in C Major: True to its title, this performance was indeed fantastic. Horowitz is acclaimed most for his different tones on the piano. Let me tell you, that is for a reason.
Scriaban: I, personally, do not like Scriaban. An acquired taste. If you do like him, however, you will by all means enjoy these two recordings of the Black Mass Sonata and the Poeme in F-sharp Major.
The Chopin: The Mazurka is the greatest mazurka recording I have ever heard, period. The Etude is technically flawless and musically flawless. The Ballade. One of my favorite pieces of all time. This is my favorite recording, simply. It is quite, quite unbelievable. I wept. Every theme Chopin includes, Horowitz includes with care. This piece is one that takes a long long long time to figure out. Musically, it is one of the hardest. Horowitz seems to finally understand it after having played it for almost forty years undoubtedly. I have heard roughly 10 or 12 recordings of this piece, and Horowitz's trumps all.
The encores: Debussy, Scriaban, Moszkowski are all wonderful in their own right, but Traumerei is practically Horowitz's child. People in the audience were weeping when they heard this piece. I went in with the intention of not weeping, and failed miserably. It is the singly most beautiful performance I have ever heard.
Buy this set. You will absolutely not regret it.
