This is great news, as this is the only one of the "Classic Seven" that never had a quad mix back in the day, and consequently never had a 5.1 SACD release because there was no quad mix to go back to.
Quite an astounding release out of nowhere, as back when SACD was hot at retail would have been the time to do a new 5.1 mix to call attention to the original Moodies 5.1 SACD program.
No more home upmixes of this album, and hopefully whoever does it, does it well. Still, it's hard to believe that it will be a complete new remix. I mean they could pull the old upmix trick on the tracks where the masters were lost - if they were lost. Time will tell I suppose.
Fingers crossed and ears ready.
