I have to confess that I don't really like the way the pianist is playing it, it doesn't really sound like a work of Rachmaninoff's. However, I think that it is interesting to have a wind band instead of the whole orchestra, and I think that it is done really well - but I have to say that I prefer the original. In my opinion, it should be played the way Rachmaninoff wrote it, who can say that they understand his piece better than himself?
