Sorting calendar events - Ordering events per day by taxonomy

I am trying to order (sort) event listings (per day) by venue (taxonomy term) in a functioning calendar that lists events that occur at multiple venues...

I'm hoping to populate calendar like this:

DATE 1:
An Event (node) at Venue H
An Event (node) at Venue W
An Event (node) at Venue S

DATE 2:
An Event (node) at Venue H
An Event (node) at Venue W
An Event (node) at Venue S

Right now the calendar is populated according only to time.

I have had little luck getting listings to display in an order influenced by multiple sorting criteria (at least this taxonomy).
Not sure how to proceed?
Thanks!
