The Night Before
We tech tonight. And tomorrow we open.
Here's the difference between tech rehearsals in the theatre and tech rehearsals in the dance world. In theatre, tech happens more than a day before you open and then you preview to work out the kinks; in dance, tech happens sometimes on the actual day you open. On Broadway, there is probably an hour to an hour and a half of tech for every minute of the play, minimum. On Broadway, they use infra-red cameras to choreograph scene changes in the dark. On Broadway they work it until they've got it right.
Broadway is for pussies.
First un-interrupted run with the costumes and lights and sound and everything? Probably tomorrow, with the gala audience.
I've watched dancers and been amazed by this a lot over the years. Sometimes it's like watching a scary movie and thinking, "Wow, no WAY I would do that."
I take it back.
