Just discovered a new and very interesting project, pairing up poets for timed, collaborative work: Likestarlings. Editor-in-Chief and co-founder, Caleb Klaces, is a former Foyle Young Poet of the Year (twice), amongst other things.
I like the fact the project pushes the idea of collaboration, emphasising the shared nature of writing. Reading sequences of poems produced by paired poets, I get the sense of the dialogue emphasised above the individual poems. One piece, Caleb writes, reads as if it is a single poem broken into sections. Others respond to each other, as if a strange object - some kind of essence of the poem - is being passed back and forth between the pair.
Mostly the poets are being commissioned at the moment, but do get in touch if you'd like to know more or be considered for a pairing. And have a read of the articles on the blog - 'Palaver' - which express very eloquently ideas relating to collaborative writing and writing collectives.
