Query: In a league of his own

In my opinion, Weissenberg blows everyone away with these Chopin concertos. I've never heard anything more poignant and profound than Weissenberg's reading of the romanze in concerto #1. Weissenberg's octaves in the rondo are beyond belief. His precise ringing tone and uncanny dynamic control throughout are without peer. The orchestra does sound a tad boxey and the low string sections are occasionally boomy especially in the fortissimo passages - consider for example the opening of the 2nd concerto - in contrast the piano is bright and crisp. Overall, the sound quality is not bad. These performances are in a league of their own, embodying Chopin's youthful exuberance and passion. Two geniuses collaborate, Chopin and Weissenberg - don't miss it!
