Being an avid fan of Chopin's piano concertos, I own about 20 or so different versions, and this one is a rather recent jewel of a find...as another reviewer said "almost too perfect", but I'd like to add it really IS perfect in many ways. Not only is the sound quality excellent, the music itself is so beautifully performed, with the subjective "right" balance between the orchestra and pianist (Zimerman outdoes himself here, really). But the most important being that Zimerman is so in tune with the emotions of the concertos, its cadences are remarkably sharp when needed, remarkably sad when needed. It's absolute perfection.
If you want just one version, this should be it. I'm not a musical expert, just a very serious musical fan, and to me, this is without a doubt, the perfect "definitive" recording of Chopin's exquisite concertos.
