ART! When you find a masters painting that has been in storage for years you restore it. You lift away the crud so you can see what is under it.
When I listened to the Atmos mix I heard separation of strings, inflections of voices, crispness of horns that I didn’t hear before. Isn’t that like a restoration of a masters art work? That wasn’t an accident, if you watch the video interview of Giles he discusses the process that was used to restore info that was on the original masters.
