Rosy Simas grew up in Minneapolis and formed her first company here in 1992, but she has also made San Francisco, Los Angeles, New York and Montreal her geographic and artistic homes. Winter/Hiver, which Simas produced last week at the New California Gallery, is her first public work since moving back here from Montreal, In this 3-Minute Egg from the opening performance, Simas talks about moving — on and off the dance floor.
