As for multiple profiles, I'm not 100% on this, but there's a difference between renaming a band an keeping the entire catalog like Electric Callboy, or leaving the catalog and starting to release under a new name like Rhino
It's confusing to see multi profiles of a same band, and not everyone is aware of it. We can add these in a different section of a.k.a to let folks aware about it.
This band's profile is 'invisible', meaning that it's much less prominent on the site - either because it's incomplete, or maybe doesn't entirely fit MS format.
