Thanks for the link, Barry. I read the article and found where it mentions M8. I don't want to get your hopes up, much less mine, that the projected M8 you mention COULD very well likely be the one that Nézet-Séguin performed in Rotterdam, as opposed to Philadelphia. Of course, we would prefer that it be Philly! If it turns out not to be Philly but Rotterdam, my supposition is that contractual and royalty issues may be the intervening problem for it not to be Philly.
I've seen elsewhere (I think on Amazon) where the Rotterdam 6-CD box will eventually become available.
