When I click the 3 dots (on any movement) & ‘Go to composition’, the composition is displayed.
It says there are only 16 recordings available of this particular composition.
The version that’s contained on the box set mentioned above, does NOT apear anywhere in the list of recordings.
The only version matching (recorded by Martha Argerich & Alexandre Rabinovitch-Barakovsky) is the one on the Qobuz album “Martha Argerich Plays Mozart”. Link to Qobuz album.
OK, different problem then. I realize I don’t really understand what you described in the first post.
You go to the composition of this recording on Disc 9, the one marked yellow
It says there are 16 recordings.
Correct so far? But you expect more?
Then you say “The version that’s contained on the box set mentioned above, does NOT apear anywhere in the list of recordings.”
That’s the part I don’t get. I thought “the box set mentioned above” IS the one you showed, with the yellow mark. Is there a different box set mentioned?
One possibility is that two composition entries exist for what is actually the same composition, and each one shows a subset of the available recordings. In this case, you can go to My Library > Compositions in the side bar, select them both, and merge them
