A young woman is strung up above the stage, a delicate lattice of red ropes criss-crossing the bare skin on her thighs and ribs, leaving an exposed patchwork of flesh. It’s the startling opening of Everything I See I Swallow, a show that won a Fringe First at the Edinburgh festival this summer, a two-hander devised by actors and aerialists Maisy Taylor (the suspended woman) and Tamsin Shasha with director Helen Tennison.

What Taylor is demonstrating is the art of shibari, the centuries-old practice of Japanese rope bondage, which began as an elaborate way for samurai to restrain their captives and has evolved into an erotic art. Your first thoughts might be: this seems like a niche interest. But it’s the spark for a piece of theatre that speaks to something universal and pressing, about the rights of women over their own bodies, the ramifications of digital life, and that knotty old question: can it ever be empowering for a woman to take her clothes off in public?

Shasha plays Miranda, a woman appalled to discover her artist daughter Olivia (Taylor) has been posting semi-naked pictures of herself online. Their ensuing standoff is a primer on contemporary feminism and navigating sexuality in the internet age. That the pair have done their homework is evident (thinkers from Andrea Dworkin to Beyoncé are namechecked) and the occasionally heavy-handed script can be self-consciously learned, but the fact is it’s fascinating territory, constantly evolving and full of complexity.

The pair act out an unusually frank but believable mother-daughter bond, the calm self-possession of Taylor, 25, versus the fraught energy of Shasha, 53. The aerialism is contemplative and illustrative, the umbilical attachment of mother and daughter stretching as the girl grows up, or Miranda tying herself in literal as well as figurative knots with the argument at hand. Different modes of text layer up: conventional scenes, direct address to the audience, quotes from feminist theory and naturalistic voiceovers.

Taylor’s monologues are some of the most authentic-feeling sections and her character is semi-autobiographical. “It’s something I’ve been exploring in my life anyway,” she says of the show’s subject matter when we speak after a sold-out performance at London’s Jacksons Lane arts centre. “I spent three years at circus school and when I left I started working as a cabaret performer in a strip club. I was performing rope shows, mostly naked, and I was trying to explore why people have such strong views on women in sex work and women posting nude photos online. And whether that behaviour can be empowered or whether it’s always part of the problem.”

Some of the things Taylor speaks about in Swallow raise important questions about how we bring up girls. As a child she was always told how pretty she was, to the point where she began to resent the assessment of a quality that seemed nothing to do with who she was. It drove her to dissociate from her body, she tells us, and the unexpected way she reconnected was through shibari, finding complete peace in deliberately giving up control.

It’s a fascinating personal history, but incorporated into the show’s narrative it raises plenty of questions: Who holds the power when you put an image into the public realm? How do you manage the gap between intention and reception? After all, one person’s art may be another’s porn; you may feel empowered but you can still be objectified.

Olivia’s fourth-wave feminism jars with her mother’s outlook, with Miranda struggling to protect her daughter and her generation’s hard-won gains in equality. Shasha feels similarly. “But we do need to talk about these things,” she says. “I want to have that conversation. I’ve become very woke making the show.”

I ask Taylor about her own mum’s reaction to what she does. “My mum’s great, she’s very supportive,” she says. Taylor’s parents were part of the new age traveller movement and very open-minded. “My family trust that I have really good reasons for doing what I’m doing,” she says. There’s a condescension towards women who are “outwardly sexual”, she thinks. “It’s, ‘They can’t possibly know what they’re doing, they need to be helped.’ And no one who knows me would ever think that.”

For Taylor, all her work, whether shibari or circus or strip-club shows, is a form of research, and Swallow is a vehicle for discussion, not a conclusion. “The fact that we don’t know where we sit is part of it,” she says. “I know there’s something wrong with the sexualised imagery we see of women every day, but I don’t think the answer is to totally strip sex out of life – it won’t work. We need to normalise sexual desire and expression rather than having it as this secret everyone carries around with them and is terrified of because it’s somehow anti-feminist.”

Challenging, provocative and funny, too, Swallow is a brave dissection of the intergenerational divide where the personal is undeniably political.
