Greetings, makeup brain trust;

I am going to give a friend a hand with her makeup one of these days (she's a lead singer in a death metal band and will be having her first "real big" performance in the weekend) and I am looking to find very light and/or white foundations and powders for performance.
The labels I use for my normal BD performances do not carry shades as pale as I need (I'm sure you're familiar with this problem.)

Of course, it has to be very durable.
It has to be able to "hold on" even if there's a lot of sweating going on.
And especially in my case, it has to give a lot of concealment, since I turn red as a boiled lobster whenever I get the least bit hot and sweaty.
I have actually been considering genuine theatre makeup for myself because I really sweat a lot and turn so brightly red.
Yeah, I know it's a lot of info, but in this case it IS highly relevant.

Which labels do you prefer and why?

Do you use both powders and foundations or both?

Hope to hear from you highly experienced performers and make up savvy ladies out there.
