I have to agree with "A music fan" is his review of March 2003.The piano used is poor, and not even all that well in tune. The recorded sound quality is muffled and 'processed'-sounding.And the playing, I am afraid, is an insult to Joplin. What a pity to produce so full a set, and to do it so badly. A travesty.If you want a superb Joplin set, played "as wrote", on a good concert grand and played with verve and style, and well-recorded, it's got to be the new Guido Nielsen 4 CD set on the Basta label (Basta 30-91262).For a really fine single CD recorded on a top-notch piano and with playing that brings out all the elegance in Joplin's music (which it isn't wrong to do - Joplin put it in there), try the new Naxos CD played by Alexander Peskanov (Naxos 8.559114).The Zimmerman set, I am afraid, must be consigned to the dustbin. A pity.
