I remember that now.
I never got the US box set because, IIRC, one of the CDs was defective on all copies and rather than repress it, Sony just sent people CDrs which I thought was pathetic.
I assume this will be a new pressing, but will wait a bit to see for sure. I have the highlights, and an earlier single CD called Cookin' at the Plugged Nickel. I also downloaded the entire set for free from my Public Library, a service called Freegal. I believe it is technically legal, it is a subscription system they pay into. The labels are OK with it, especially Sony, although I doubt the Artists would be if they knew. I got a lot of out of print recordings this way, and also bought quite a few after as physical CDs because I liked them so much.
