The project initiated by artist and filmmaker Beatrice Gibson and typographer Will Holder, based on the eponymous score written by Cornelius Cardew in 1967.

In 2010, a production process was instigated by filmmaker Beatrice Gibson and typographer Will Holder, with the intention of using British composer Cornelius Cardew's musical score The Tiger's Mind as a means of producing speech. Since the score concerns the changing relations between six characters in production, practitioners from other fields (musicians and visual artists) were invited to three conversations at Künstlerhaus Stuttgart, Kunstverein in Amsterdam, and CAC Brétigny. 

After each conversation, a printed document was made and distributed amongst the characters, to serve as a score for subsequent conversations. Any other ends would be found in conversation. After some time it became clear that a film would be made: Beatrice Gibson's The Tiger's Mind. This book is a document of its making.

From Audre Lorde and Adrienne Rich to Basma Alsharif and Pauline Oliveros, Deux Soeurs brings together a chorus of voices that explore representations of parenthood, friendship, and disobedience.

The book acts as a reader to artist Beatrice Gibson's films, I Hope I'm Loud When I'm Dead (2018) and Two Sisters Who Are Not Sisters (2019), and includes material that informed Gibson's working process, together with the artist's texts and notes used in both films. Turning to the figure of the poet as a guide in times of chaos, Deux Soeurs presents a framework for an ethics of artistic and social collaboration.
