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 uncommon for jazz ensembles that release multiple albums.
Here’s my attempt at splitting the text from the covers into artists and titles:
- Guillermo Klein - Los Guachos II
- Guillermo Klein - Los Guachos III
- Los Guachos - Filtros
- Guillermo Klein | Los Guachos - Carrera
- Los Guachos - V (perhaps the title should be “Los Guachos V”, but the name only appears on the cover once so I’d probably only enter it as the artist)
- Los Guachos - Cristal
My default would be to just enter the artist credits as they appear to be printed above per Style / Artist Credits - MusicBrainz. The obvious downside of that approach is that the first few albums won’t be listed in Los Guachos’ discography and the later albums won’t be listed in Guillermo Klein’s discography. It’s extremely likely that a future editor will think that those albums are missing and re-enter them with a credit for the other artist.
I’ve seen proposals for making discography pages additionally display credits for artists that are linked with “eponymous member” relationships, but that wouldn’t help here since this isn’t actually an eponymous group.
I can see that https://www.discogs.com/artist/4474550-Los-Guachos tries to solve this by just crediting both artists for each album regardless of how it was actually credited, but that approach doesn’t align well with the MB guidelines.
I think that my preference would be having some sort of artist-artist relationship indicating that one artist’s credits should be included in another artist’s discography, but maybe that would have other downsides. Perhaps it’d be better to have an artist-RG relationship saying “also list this RG in this other artist’s discography”. Just brainstorming here, though.
