But the doubt stays present just until the premiere. It is rare for a producer to be able to intervene efficiently in the process of a creation; rather we influence it by optimizing the working conditions. And if despite all this we realize during the rehearsals that the show is not fulfilling our expectations, we accept it and we present it. We never cancelled an announced production. It is a power full of obligations. It is a fragile power. Without enough positive response from the public or the press it is impossible to impose an artist. But we can continue to support him for 2 or 3 projects and hope that he will find his audience. The power of obstinacy. There are many examples of artists who succeeded after a difficult start; recently at the Festival d'Automne it was the case with Steven Cohen, Richard Maxwell or the composer Mark Andre. But also many others over the years: Merce Cunningham, Helmut Lachenmann or Richard Foreman at their beginnings. In the end, it is a power that compre- hends failure, a production cannot fulfil expectations; however, if we are convinced of the talent of an author, we can continue the collaboration... for quite a while! It is with anxiety and fever that this power is exercised, intuition and reflection are essential, each decision being full of consequences for the artist but also for the backer.
