Joan Retallack discarded some books and journals from her personal library. This act of elimination turned out to be a recycling and archiving in practice, she produced a poem called ‘Not a Cage’ after John cage.
Her poem utilised beginnings and endings of all the books tossed away, using a combination of chance and intuitive composition.
Al Filreis and Danny Snelson (from the show) deemed that such a work was just a further step along the path the poet has already travelled. To ‘assuage’ the guilt of throwing these away, having not read them, she produced something archival. Questions were possibly: “What will happen if I do this?” “What coincidences will occur?” “What sense will be made that I cannot predict?” and now “Where is it from?”

Not a building, this earth, not a cage,

is possible I could not tell

to make live and conscious history in common

and wake you find yourself among

and wake up deep in the fruit

Did you get the money we sent?

I smell fire

God, say your prayers.

You were begotten in a vague war

The shadow of the coup continues to hover over Spain
