If in doubt: create a new artist, and link them via „also performs as“, I guess.
I think this is also the escape route out of this Place pickle: end the old one, create a new one on the same geographical location. A suitable relation to link them („succeeds“ and „preceeds“ or „succeeded by“) is still lacking, though.
(Edited to add:)
I’d only do this for places that are arguably still relevant (like the Lakewood Church Centre). Places that became an office building I would just end. I’m totally with @chirlu, we’re not Openstreetmap, and an „ended“ Place does not mean the building is no more. Maybe the end date should be renamed to „ceased function“ or something.
