"K makes a choice to come and see a play; he could not predict that he would not see the play. The act of choosing does not determine the outcome. Circumstances change, events happen. K cannot accept these changes at first; he arrives quite assured and certain of his purpose. K believes in hard concrete facts and tangible outcomes, but this could very well change too. This new work is inspired by Franz Kafka’s The Castle."
There's also a review up on the Scotsman website.
