I entered this edit for now because both artists were already in the database, but should they be merged and treated as aliases or left separate?
I agree that is a merge and alias Artist. Especially when they have put out so little work anyway.
If I get it the right way round - he performs with the fancy long name, but the writer\producer credits go to his legal name. Seems a logical setup. As long as there is some kind of link that backs up the “same person” claim.
I’ve seen plenty of other examples here at MB like that.
He may even be changing name with each Project.
Follow down the Rabbit Hole to Discogs and you find he also has other names too:
