We could very easily drift into a heavy discussion of magic Vs flourishing here but i know how may times this has been covered so i'll keep my distance from the battle and pay focus to supporting the two as positive equal opposites.
I think flourishing deserves an audience so i never just flourish for myself or my own dexterity, it's something magical and deserving to watch and very satisfying to achieve a skill such as flourishing and the reactions it can cause.
(Hopefully) you'll never see a video of me performing flourishing and magic at the same time, although I do flourish in performances, it's always at or toward the end and there's a very good reason why...
If you perform a series of elaborate and astounding flourishes for your audience and then follow it up with a trick, you can't expect good - or as good as reactions that you would have got from doing the trick without first flourishing. People who see you flourishing won't be surprised that you can manipulate the deck with a simple magic trick, as magic next to multiple-packet flourishing just seems okay and not amazing.
In most of my performances i'll act like a stranger to playing cards because I'm not out to show my skills of manipulation or control, I want my spectators to see me as one of them, not only does this offer a serious level of rapport, it also diminishes expectations opening a perfect platform for something unexpected.
Toward the end of the show i'll then display a few flourishes, which will play as a bonus "wow, not only is he a great magician, he can also do crazy things with the cards" this is so much more rewarding than "he's great with cards... oh, and he does magic too."
If i didn't respect my audiences enough to think this way, Dangerous would have probably been one mashed up version of a magician showing off between his tricks, magic deserves it's own ground that shouldn't rely on the attention grabbing basis of flourishing. I see a lot of magicians flourishing between performances, but all it does is confuse my decision on the spectators reactions, are they reacting to the magic or the flourishing?
In summary, it's all about expectations, id rather play with my spectators expectations with magic than instantly fulfill them with flourishing
Savvy?
