Atmos is nice for solo piano but less essential.
Agreed--though it will be nice to have this on BDA in a hi-res format
The Karajan one is potentially more interesting
What do we know about the sources for these Atmos mixes? Is it likely they'll turn out any better than the Karajan Beethoven set?
The Atmos stuff that DG have been releasing on Tidal is really tame, for the most part: faint hall ambiance for both rears and overheads.
