Album Reissued Under New Artist Name

Release titles that later become artist names

Los Guachos is an ensemble led by Guillermo Klein. There’s currently also a Guillermo Klein y Los Guachos entity in MB, but I have open edits to reassign its credits to the two individual entities so that it will be deleted. Looking at the cover images of the releases on Guillermo Klein’s Bandcamp site, it seems like he credited himself for the first few albums and used “Los Guachos” in the album titles, but he later shifted to crediting “Los Guachos”. In my experience, shifts like this aren’t …

For the original example, I think the guidelines are pretty clear that the old release should be credited to “Bird” and the new release should be credited to “Emmas”, and that both releases should be in the same release group. There might be room for arguments about how the release group should be credited, though.

Style / Release Group - MusicBrainz says that “the [RG] artist should usually be the same as the first release,” but it’ll then only show up on that artist’s main page. I’ve seen suggestions to credit the release group to both of the artists so that it’ll appear in both of their discographies, but that feels somewhat at odds with the guidelines to me.

Would it be reasonable for an artist page to display all release groups containing releases credited to the artist, even if some of those RGs themselves aren’t credited to the artist? Would this be too confusing? Are there cases in which it would produce undesirable results?
