This is an enjoyable CD, well recorded demonstrating impressive piano skills. If this is all that works for you, it is 5*. However, it is pumped up Chopin, not the reflective Chopin I expect based on the notes. Without a formal music education I don't know if Ms Argerich's interpretation is within the sphere Chopin intended. I believe it is inconsistent with other familial Chopin compositions, and note others have played these differently, expressing sensitivity lacking here. Ashkenazy's recording sounds more authentic. I like his performance very much however, audio quality is poorer than desired. My pick is the recent Linn issue by Ingrid Fliter, not as flashy as Argerich ... which again begs the question what artistic messages are intended to be conveyed? You decide. I started to rate this 3* but decided not fair. But it can't be 5* because it isn't Chopin. A similar case with a distinction .... Horowitz recording of Liszt Sonata in B Minor is a somewhat idiosyncratic interpretation, spirited. The difference is for Liszt this is OK (vs Arrau), noting Liszt was one of compositions were written to demonstrate keyboard artistry. Rachmaninoff's concertos are ones to demostrate keyboard artistry, although require large hands or the pianist will drop notes. Few pianists have hit all the notes in the 3d. I don't see Chopin's Preludes as ones to dazzle. Having more than one rendition is good. I'll see which I listen to more and donate the other.
Update: Since I first wrote this I've listened to both Argerich and Fliter numerous times ... call it an experiment. I enjoy Argerich more however, I stand by my assessment above. I can't call this a 5* product because fundamentally it is a deviation from Chopin. It works for me to own both.
