Release title (and subtitle) naming (Classical) :guidance request

[mmirG]

Forking from How to change stop-gap “release group” members to series?

I am set to add some releases that are members of a complex group of releases. (At least one 32 CD box-set and also multiple re-issues of a series.)
I would like to get the naming right this time. (There are over 60 discs and releases to add.)
The naming of the release will also be carried through into RG and series’ names.

These are classical releases.
The following examples are samples from one release group.

Early Recordings by the Pianist: The Condon Collection: Rare Recordings

Masters of the Roll: Rare Original Recordings From the Reproducing Piano by the Great masters of Classical Piano 1904 - 1935: A 32 CD Catalogue: Disc 20

The Masters Of The Roll - Vladimir De Pachmann

The Great Pianists, Vol. 1 Vladimir de Pachmann

How should they be named?
(There are currently multiple errors in names and label. Please use the CA as per CSG.)

This would be easier once the cover art archive comes back up. But for the one that can be seen right now, “The Great Pianists, Vol. 1: Vladimir de Pachmann” is probably ok, as would be simply “The Great Pianists, Vol. 1”. It should be in a “Masters of the Piano Roll” series, but that doesn’t need to be in the title. Also possibly in a separate “The Great Pianists” (sub?)series. As long as all parts of the same series are somewhat consistent with each other, exactly how they’re titled can be based on the editor’s preference really
