I second the idea that it would be useful for a new place for NLP and hypnosis in the context of performance, but why stop there? NLP, psychology, hypnosis, persuasion, influence, language patterns, pattern interrupts, guided imagery, time dilation, scripting, patter, phraseology etc. are all viable techniques and are used by mentalists and I'd guess magicians too. I can think of at least one well known performer who has used quite a few of the above to build a reputation.
The methods used clinically in hypnotherapy still work in a similar way to stage performance. The techniques used can be somewhat different in terms of speed, but it's still essentially the same thing.
If you're into bizarre magic, surely some of those things are extremely useful for patter, setting the scene and atmosphere, influencing the specs to believe in whatever it is you're trying to sell them? If I were setting up a seance for example, I'd definitely be using hypnosis and at least thinking about how NLP could help! People are in a highly suggestible state before they even arrive. The possibilities are absolutely endless and get my juices flowing just thinking about it. Sorry, got a bit excited there!
I'd have thought things like Wonder Words come into this subject area too. How many posts are there from mentalists where it is at least mentioned how important wording and phrases are? Many effects rely solely on what is said, so the language is one of the vital tools available. NLP and hypnosis (particularly Ericksonian) are very powerful tools to aid language use. There is a lot of crossover between these disciplines and it's worth looking at imho.
Just my 2p worth
