Jani Lauzon is a Métis multidisciplinary artist who says she can’t stop creating. Over the years, she’s eked out a living as a rock and roll singer, an actor on stage and screen, and a puppeteer for Jim Henson, among other things. She talks to Tom about turning to art as a way to cope with a turbulent childhood, and how all her talents collide in the new play “Prophecy Fog.”
