I have just ordered a CD of Krystian Zimerman and the Polish Festival Orchestra performing Chopin's Concertos. The samples were quite promising, though unfortunately they were all only one minute taken from the beginning of each movement, which, as you all probably know, is mostly orchestra, though I got a good taste of Zimerman's playing with the first minute of the 3rd movement of the F Minor.
And really, the bits of the other movements speak well for the musicians in the group and Zimerman's leadership of them. Some of the movements are played a bit slower than I am used to, but the musicianship that is shown is quite above that which I have heard in other recordings of these concertos.
I will give a full report when the CD arrives.
