Thanks for your contributions
I do have some notes on that release, nothing major, but MB has a few details that are hard to pick up on right away.
Firstly, it can't be a digital release and a CD release at the same time. If you're wanting to add a digital release then the type will probably be 'Digital Download' - in this case your CDBaby source only has Digital Download available so that would be the way to add it.
Similarly, even if the artist is from the US, digital download is usually [worldwide] for release country, unless it's set to only be sold in certain countries (eg only available on amazon.jp would probaby be a Japan release). I think CDBaby offers the same products worldwide.
With the label I think it might just be 'Sulis Minerva Records', Raleigh Holmes might just be asserting her rights over the release by putting her name in as well, but I'm not 100% sure so it's fine to just add it as you did/ as CDBaby had it.
Hope that's all clear enough, feel free to ask any other questions you might have!
Unfortunately it's a known issue that MusicBrainz doesn't display artist associations that well.
The correct relationship has already been set here:
(member of: The Scarlet Furies )
And that's pretty much all you can do.
You can add credits (eg played x instrument or composed x song) to tracks/ albums by The Scarlet Furies which will add more relationships between them, but they still wont be displayed on Raleigh Holmes' overview page.
