[Plugin: Widget Logic] to display on [Event Calendar]per specific event category

I am trying to get “Widget Logic” to display widgets on specific “Event Calendar” categories.

I have a handful of music categories set up using the Event Calendar. My intention is to have a widget display on only the “hip hop” or “rock” post pages, etc. I am a novice to coding but I understand through the Widget Logic information page that I need to get some conditional variables set properly.

The example they gave that I have been trying to use is:
is_category(array(5,9,10,11)) — category page of one of the given category IDs

I found a list of classes that I thought I would need from Event Calendar here:
http://docs.tri.be/Events-Calendar/index.html

Can someone assist me with the proper code to insert into Widget Logic to allow the widget to display per Event Calendar category?

I think you sincerely for your time and assistance.
