It isn’t one performance, it’s on for 10 days, with interviews for 3 hours on some days and 8 hours on Saturdays!
Also, from the description on BAC website and the linked First Trimester website, it is far more about the conversations about what being a father / parent / donor if sperm entails, and what qualities we should value.
Participants in the interviews don’t even have to be able to produce sperm. So women can take part.
Grey area for me. They are not staying that this show (durational performance art) is an audition and will lead to choosing the donor. It is billed as being about conversations about parenthood, but they might, by chance, find the person who is the donor.
Really unethical to use a show to find a donor, less so to use the premise to invite people to have conversations in which they are asked questions based on the artists explorations about what parenting and bring a donor is.
