It is possible to tell MusicBrainz what roles members of a given band/group has (see e.g., Tiny Hoedown's relationships), but CritiqueBrainz currently simply adds the member(s) several times to its own listing (see e.g., Tiny Hoedown's CritiqueBrainz page). Your task is to make CritiqueBrainz smarter in how it handles this.

Notice that sometimes bandmembers are given multiple times because they've been members for different periods (e.g., look at The Drifters' CB page), which should still be accounted for, so be sure not to make your algorithm too smart. 😉
