I have listened to a lot of Chopin interpretations over the years. After an inability to master the technical difficulties, so that you can actually hear the individual notes, the most common problem is failure to empathise with Chopin's emotionality, so that it comes out flat and mechanical. Argerich is just one of several pianist suffering from this defect. (She is absolutely fine with other composers.)
Blechacz's performance is technically flawless, and I can't remember such crispness of playing with any other Chopin recordings. His Preludes are a revelation, they take the breath away, I was totally bowled over. If it doesn't sound too precious, they are so brilliant I actually find it difficult to listen to more than 2 or 3 at a time.
The sensibilities expressed here are undeniably romantic, though never maudlin. The tone is assertive, at times it almost sounds Bach-ian in the confidence of the notes. If you don't play Chopin romantically, you shouldn't be playing him at all - he is the quintessential Romantic composer.
The one possible objection is that sometimes B's pauses, which he extends for effect in one or two places, can seem just a little too long.
Overall, however, I found this recording utterly brilliant. Until now, my top 3 Chopin players were Pollini, Ashkenazy and Tamas Vasary in the lead, but Blechacz has now displaced him, at least for the time being. More please.
