I agree with Wes.Wesley wrote:I think over explaining things that don't necc. need an explaination kills the energy and treats the audience like, well, less-than-smart.
Yeah. I think set-ups can flavor or condemn a show.
A show with a gimmick needs very little, such as a Cops & Lawyers, Start Trekkin', or Whirlded News. People get the gimmick and that's probably why they came to begin with.
But I think, as Bob said, there is a certain "base-level" explanation that must be made for people new to improv in less format-driven shows. You don't need to explain "This is called a revolving door edit and it means this and we'll be doing an Armando which follows this pattern," but I still maintain that a lot of people confuse "suggestion to inspire our show" with "this will be a show about your suggestion."
I've seen it both in reviews and in person when an audience member doesn't understand why their suggestion was not used verbatim or in some overt way. This is where I think a two sentence intro (and the demeanor in which the suggestion is taken) can often go farther to audience joyment than just saying "Can I get a word beginning with B? When the lights come up."
(Because then a number of people will expect the show to literally be about "bees" not merely "inspired" by the word.)
My 2 cents.
Also.
If you're doing an Armando and you don't say that the monologues are from real life, that bothers me. I think the difference between truth and fiction can be very good for comedy. People like brief explantions for unfamiliar things.
Take a menu at a restaurant for instance, if the item is a hamburger, there may or may not be an explanation, due to the popularity of the item but if you have Santa Fe Chicken Surprise, most people are going to want to know what's in it before they take a bite.
In the same vain, some audiences members won't bite (engage themselves in your show) if you don't help to inform them a little bit.
