Keep in mind that these are the shows I picked, that I like, let's call them staff picks. I'm the staff. Chef recommends, and I'm Chef. This is, by no means, the complete schedules for all of these venues. That said, the list is long and distinguished. Here are my combined show listings for a great summer of entertainment:

Last but certainly not least there are great, free concerts on the Danbury Green, all summer long starting June 1 and running through Sep 7. It's "Summer in the City" presented by City Center Danbury. Tim Sheehan did a great article for I-95 just the other day with the complete show listing. 
Your summer is planned, you are welcome. Compliment me on my very broad taste in music and comedy later, I'm busy now.
