In fact, full historical membership lists for orchestras would be fantastic data, even if it takes three pages to display it all ![]()
If we know who performed specifically on each track, I see no reason not to credit them. A different question is whether we really know this (are they all on all tracks, or did some members play on some but not others?).
The recording artists are set to the credited ensembles, which seems correct. As per the recent discussion in What to do? Trio name and individual members credited some of us like having the ensembles also linked as relationships even if the members are known, while some others don’t, but it’s in any case not wrong. Ideally we could say “X performed on Y as a member of Z” but that’s not something we can do at the moment.
