Master Release:
https://www.discogs.com/master/create

RSG §2.2.3 There is no limit to the number of artists that can be listed as 'Main Artist', but the release itself must show the intention that the artists are to be taken as the main artists on the release (or to list the artists in a way that doesn't allow us to differentiate). See RSG §2.3.1 for special use cases for when no specific artist is credited on a release.

In Groups:
RSG §18.5.5 It is possible to mark an association between two artists inactive or defunct by placing an " [[X]]" (In other words: Space, bracket, bracket, capital X, bracket, bracket) after the group name in the Submission Form. This will cause the names involved in the inactive association to be crossed out in the respective Members / In Groups sections on the Artist pages. A group membership should only be marked as defunct if the member left the group while it was still active. This means that if a group breaks up, or a project is retired, all artists who were members at the time of break-up or name retirement should remain listed as active members.
