This morning I watched recording of a local magician’s livestream of magic. It was pretty rough to watch, it was almost four minutes into the video before he started doing a trick.
What happened the first four minutes?
He spent that time apologizing for not being able to do a coin trick. Then explaining why he couldn’t do it. Finally he apologized for his livestream being a livestream and not an in person show.
When you perform, you should be performing! Don’t tell me why you can’t do something, or the limitations of the venue (yes, livestream is a venue).
In a live show, would you start by apologizing and having no entertainment for 4 minutes?
Heck no.
Do your opener, once you’ve established yourself, you can mention a limitation as it becomes relevant.
