I owned this album in vinyl years ago, and loved the Bach organ transcription. Listening to it today, I still find the transcription appealing, but what really makes this album a work of absolute magic is the playing of the Mozart compositions. The effect is difficult to describe, but it brings to my mind cold, superb, German white wine. If you haven't discovered this, the Germans are no fools. They keep the best wine for themselves, and export what they wouldn't drink. Good German white wine is truly the nectar of the gods. So, when I listen to the Mozart pieces, I think of German wine; they both have huge gravity, a lovely but not sticky sweetness, also huge amount of life and energy (yes, wine lives and breathes), and they both sparkle brilliantly. I know this is a bit poor, but it is the best I can do. The quality of Horowitz's interpretations and playing is a treasure to hear. The downside is that this is a live performance, and I have never heard so much intrusive coughing. I still believe it is worth having the album for the quality of the playing.
