I'm puzzled that no one seemed bothered to review this recording... but it's undoubtedly, a classic, both in Pollini's personal recording history and among other recordings of the preludes. Yeah, the preludes are the sort of thing that necessarily gets a different treatment with each different artist... but despite the subjectivity I cannot help but agree that this IS the standard! It's a recording that I constantly go back to in order to get a sense of the "overarching idea" of each piece... As it seems to me Pollini more than anyone else succeeds in bringing out the underlining structure of the music. Yes, Pollini is often criticised for being a bit too "cold", but there's no evidence here whatsoever. Listen to Nos. 9, 18 & 24 and it's amazing how much passion and tension is built up under seamless control, and the unrelenting rigour here only brings out more the power and heroism of Chopin.
If you don't care much for Pollini as a Chopin interpreter than think twice after hearing this!
