Now I know how Rubinstein got to be 95 years old. At nearly 50, he was still playing a young man's Chopin. Compared to his 1960s recordings, these 1946 performances are more impetuous, more driven (he actually sounds clangorous for a moment here and there--unheard of in the later recordings), more fiery, less profound, less polished. I bought this CD on impulse, to fill the gap left by the omission of the Preludes from the 1960s recordings, not realizing how old its content is. It was remastered from 78s and bears the continuous pops and clicks to prove it. Enough techno-wizardry has been applied to greatly reduce the noise from the actual levels found in playing a 78, but that's the best that can be said for the sound. This CD is well worth having if you are a devoted Rubinstein fan, but otherwise, look elsewhere. His later recordings are better in most ways (vivacity excluded) and even my old Ivan Moravec CD surpasses these Preludes.
