The Blue man Group performance is excellent for someone wanting something different. They are highly skilled in a few things. (I have never seen anyone so skilled at throwing and eating marshmallows as they are.) Audience participation is expected for parts of it.
Having only been once, I do not know if the show varies, or is basically the same each time. Of course, when the audience is showcased, that changes the dynamic. I recommend going as a group, because having someone to express surprise with, or did you notice this? enhances the experience.
I wondered how they could do this three times a day. Then, I realized that since the three blue men never say a word, that everything they do they do with expressions and actions and a futuristic computer narrator, even if one of them was tired, no one in the audience would be able to tell.
