Sort by artist album year where there are multiple albums in one year

I have some albums by artists that have multiple releases per year. I would still like to sort these chronologically. Is this possible?

Do you have the more exact data?
I would suggest that you use RELEASETIME for any date having more than 4 digits.

The DATE field is somewhat widely used with longer dates if needed. (It is actually called date in most formats except those that use the Ape tag.) With ISO date format yyyy-mm-dd, you can easily expand it with more precision while still keeping it sortable alongside plain year.

Specifically, I'm looking at Buckethead releases (Pikes). So far prefixing "Pike NNN - " to the album title works - a bit wonky though. For example:
Pike 038 - It Smells Like Frogs

Does this answer where the release date is stored in the tags? I don't see it.
So: which field would contain the data to sort by?
