Well, this is really a sampler (disc 1 entirely at least) of the "85th Anniversary" series of reissues, mainly in Japan, and in a sense the Tone Poet series.
The UHQCD series from Japan. . . has nothing of the first decade of the label. I don't know why. I love that stuff, and each time a decade goes by and they reissue one of them the sound is so much better--right now they could really present this music very well. But yeah, that has never been a focus of the label or many of the fans this century, and the 85th series and this compilation reflect that, accurately, right or wrong (wrong imo).
