This one has transfers that are uncredited (my guess is that they are using transfers Bernie Grundman did for the Japanese releases of the last half decade) and mastering by Malcolm Addey.
I’m not as big a fan of Gray/Hoffman Blue Note material as jazz nut is. . . I often have preferred Japanese reissues to those by a hair. Anyway I had the most recent cd Japanese reissues of much of this material as well as domestic reissues . . . and boy does this set sound good in comparison. Some of the albums sound eerily close to the Japanese which is why I suspect the transfers were first done for those. Anyway I truly enjoy the sound and I truly enjoy having each album with the same transfers and mastering. And of course the music. . . wonderful stuff.
There is ONE alternate in the set never before released, so not a lot of new music. But some great photos in the booklet and a very enjoyable 8 discs of listening.
