“Belle Redux,” choreographed by Ballet Austin artistic director Stephen Mills and premiered by the company in 2015, is a dark reboot of the 18th-century French fairytale “La Belle et la Bête” (Beauty and the Beast). The two-act ballet was commissioned by the 3M corporation as part of a program to fund innovation in the arts (as part of his research, Mills met with 3M researchers and engineers), so it’s no surprise that it is unlike Mills’s other story ballets.
