I'd expect this is, in the following order:
Area: we default to country, unless the artist is very specifically associated with a smaller area (guideline). In this case, is Zoo specifically seen as a Cincinnati artist?
Begin Date: since Zoo is set as "Person", this is birth date. Obviously, this artist wasn't born in 2012, unless he's very precocious.
Begin Area: I assume this was removed because since the date was added for the foundation of the "band"/project, the area is likely to have been added with the same idea in mind, and the guy might not actually have been born in Cincinnati, but you'd have to ask @stupidname about this specific bit.
