These selections are widely recognized as among the most important recordings in the history of jazz, and rightly so. Included are the definitive versions of many of Ellington's (and his associates') most inspired compositions, performed by one of the greatest bands ever assembled. The musicianship is superb throughout, with absolutely stunning solo and ensemble work on track after track, particularly on the instrumental selections that make up the bulk of the set.
To my ears, the sound quality is astonishingly good. I've been listening to this material on various other compilations (Bluebird's "Blanton-Webster Band," the relevant volumes in the Melodie Jazz Classic label's "Chronological Classics" series, an RCA "Jazz Tribune" set, etc.) for years, and I'm amazed at how much better this issue sounds than any of those. It's true that there's a bit of surface noise, but as one other reviewer has already noted, the problem with noise reduction is that when it's used to excess (as on the Bluebird set, for example), it strips away a lot of the music along with the noise. Here, where the remastering has been done much more judiciously, the improved clarity, detail, presence, and tonal range more than compensate for the slight increase in extraneous background noise. The result is, to my ears, a stunning improvement in overall sound quality.
This is an extremely well-produced reissue that belongs in the collection of anyone with an interest in Ellington, or in big-band jazz in general.
