Hello Ruud,
That can absolutely happen. Every event can have a “Venue”, which is the location where the event happens. Having multiple venues or theaters is very easy. Furthermore each event can have an “Organizer”, which is the person or people who are putting the event on. That could be your artist. You can further categorize events into categories. An example category might be “Musicals” or “Drama”.
Someone viewing your site could easily look at all events happening within a specific Venue/Theater. Or all events from an organizer, or all events within a category.
Look at our showcase for some example of sites using venues/organizers and categories. I only know of one Theater, this one.
Does that answer your question? Can I answer any further questions? Cheers!
