What is the VERY BEST CD album you've ever heard?

I think of a couple of releases that seem to me be creatures of the CD era:

The Centennial edition of The Complete Robert Johnson brought out sounds I don't think anyone ever knew were there.

Though I don't know that it's any great shakes sonically, the 1988 studio cast recording of Show Boat was a revelatory document of what was possibly the greatest American musical.

Another monument of the CD is the encyclopedic box set: the Bear Family collections of Uncle Dave Macon, Louis Jordan and Bob Wills, the Bluebird Fats Waller and the Fremeaux Integrale Charles Trenet are particular prizes to me.

This rock vs. pop thing is obviously some sort of snobbery but I can't quite see what it's being snobbish about.  

@gumbedamit Without Googling, Queens? I know Louis Armstrong lived there.

More than any other single group, The Beatles expanded the range of what rock and roll could be more than any other group before or since. To deny their achievement by demoting it to some lesser form because of that achievement is perverse. The Beatles vs. Rolling Stones question is quite similar to the Raymond Chandler vs. Dashiell Hammett in hardboiled crime fiction. The Beatles like Chandler tend to win by acclamation, and because of that Stones and Hammett partisans push their belief with a particular zeal. Like Hammett, the one area where the Stones have the decisive advantage is toughness. The difference between the two in both cases is little more than a nickel's worth. If I were getting on a lifeboat and had to jettison either my Beatles or my Stones records, I'd keep the Beatles.
