A short question about how to properly link performers which perform as part of a group: Until now, I thought that linking an ensemble as a performer to a recording or release was kind of a placeholder for the individual performers. So, e.g. for release https://musicbrainz.org/release/ce5c9691-0b95-4fe9-8039-8b4666a4f7a7 I added the individual performers and removed the quartet, setting it as the recording artist in the process. In edit https://musicbrainz.org/edit/37627973 I was stopped from removing the quartet relationship. I explain my rationale there (seems duplication to me and the quartet is credited as the recording artist), but as I can’t find anything explicit about cases like this one in the style guidelines I am not that sure anymore. So how is meant to be?
As as side note, I think the guidlines on relationships could be a bit more elaborate on how and when to use the different relationship types (regarding discussion Questions about producer and engineer relationship types, I had completely missed the page about the balance engineer relationship type).
