I caught Strange Attractor’s Before We Begin on Saturday afternoon, during PVDFest, and afterwards everyone I explained it to had the same reaction: “That sounds like my worst nightmare!” It does sound that way, but it’s not. An intro of Victor Borge proportions segues into a participatory workshop thing that’s designed to make every single person uncomfortable, including performers Rebecca Noon and Jed Hancock-Brainerd. One person stomped out so loudly that I assumed she was part of the show. (She wasn’t.) It costs one Sacajawea to get in, and also you have to be wearing sweatpants. Reserve a seat and you’ll be sent a video explanation.
