elmore, that Moldau is a stereo recording done for RCA years after the one I grew up with, which was on Columbia - being mono, I don't think it will ever get a release.
And yes, that first box you pictured is the Columbia set - the other box is RCA - not sure if he recorded Carmina Burana for both labels, but if so I would seek out the Columbia first.
I loved this subject today, btw.
I do wonder if some of those classical mono recordings will show up. I don't mean the unique ones for which no stereo counterpart exists, but the ones like this for pieces that were eventually rerecorded in stereo. There are such mono versions of performances on all the major classical labels that a lot of people continued to like more than the later versions for one reason or another.
Oh, and I love the idea of CD sets utilizing original cover art. Absolutely love it. Just like I do when movies are released with at least a nod to the original poster art. It makes such a difference in one's enjoyment of just handling the damned things.
I'm going to do a quick browse of ye olde record collection in a bit to see what there might be of Ormandy's that's interesting.
