there is a fairly recent thread about Droneflower you might want to take a look through, if you haven’t already. sounds like a somewhat similar situation~
there were two examples given over there which might be pertinent tho~
first, I gave the example of Huge Umbrella, a loose artist collective who’s first couple albums were released under the names of the members, but according to Mumble on his wiki are, “affectionately considered to be” Huge Umbrella releases. I decided to reflect that in the artist credits
then @ernstlx showed perhaps a better example, with Chick Correa’s Return to Forever ensemble, but since their first release was credited to Chick Correa, that’s how it’s been entered
a third option not brought up in the thread, but I have seen done… you could add both artists to the release group. it could be seen by some as a “hack”, but I think it can be the best solution in certain situations
I don’t know that there’s a consensus on what to do in these situations, based on the other thread
