Visual Composer custom query with OR operator

I am working with Wordpress via Visual Composer and a post grid of results from The Events Calendar. I have the query working as long as I only want to pull from one events category but I need to pull from multiple categories.

I have tried all of the tricks using OR operators and cannot get this to work. The code I have that works to pull from one category:

 post_type=tribe_events&post_status=publish&_EventStartDate=>$today&orderby=_EventStartDate&order=asc&tribe_events_cat=entertainment

I need to pull results from Entertainment and Concerts.
