The really terrific writer Brian Dillon whose own work spans and bridges several genres, including criticism, memoir, novel, history wrote a nice essay for Frieze magazine last year on the notion of teaching writerly style in the (art) seminar room: "Does turning in the classroom or on the public stage to the question of style mean a retreat from the open field of ‘art writing’? Quite the contrary, I think. Because the crux is this: once you have delimited a certain space of experiment – delimited it precisely by its lack of limitations – what then? Where is the real work to be done?" Very much worth a read.
