If destroyed, still true (Norwich & Norfolk Festival)

Recently, social networks like Facebook have allowed us to reconnect with people from our past and perform stealthy surveillance on their current lives. Molly Naylor last year bumped into the "queen bee" of her school in a swimming-pool sauna and felt so awkward that she hid and then shuffled out of that sauna. That discomfort of her teenage memories inspired her to write and perform If destroyed still true.

In a simply staged performance piece which co-stars the musician Iain Ross, Naylor and Ross only have the accompaniment of a couple of electric guitars, a drum and hi-hat. Littered with funny and beautiful writing, this is quite a subtle performance delivered clearly and appropriately toned.

Unlike much performance art, which can take the form of a lecture or self-indulgent autobiography, Naylor creates a dual narrative – the story of her own surveillance of Miranda (the cool girl) on Facebook and another story, of a 15-year old girl today, whose childhood cliff-top home is perilously close to falling into the sea.

This well nuanced interweaving of Molly's and this modern girl's story makes you realise the mistakes that you made in your teenage years as well as the wide-eyed innocence you had then.

Besides weaving a contemporary and a 1990s childhood story together, Naylor incorporates Ross' performance cleverly. At the start of the performance, he seems like some kind of foil, but throughout his contribution increases, and he provides a welcome deadpan humour to Naylor's exuberance.

There are many performance artists now, especially on the arts festival scene, who mine their autobiographies for material. This piece is distinctive because there is a sense of self-satirising (helped by Ross's straight delivery), a subtle use of music and also a modern-day story. It is this blend of material that makes this a performance worth seeing.
