[1]investment (is) the line of connection between performer and their text or their task. When it works it is private, and often on the very edge of words. Like all the best performance it is before us, but not for us. (…) investment draws us in. Something is happening – real and therefore risked – something slips across from the private world to the public one – and the performers are ‘left open’ or ‘left exposed‘.
