Hi,
I forward a question of @adastra1 from notes on edit #43470297. It is pretty much close to previous discussion about ABBA credits on first two LP releases.
Ulaid is both a (first and so far only) release by three musicians and a band although they are more often credited with their individual names which are well-known in their musical genre.
I really don’t know if there is a good way to do this. Maybe by creating a pseudo-release?
