Chicago artist Nick Cave has made it official now, at the Park Avenue Armory in New York: He wants to use massive art/dance projects to inspire and encourage those feeling pretty down these days. “‘Empowerment’ is the word that performers have been using to describe their take on the project, and what they want to convey to the audience, [a dancer said]. In an onslaught of negativity, ‘you have two choices,’ he said. You can be discouraged and tormented, ‘or have the audacity to say, ‘I’m not going to let this break me.’'”
