To see the most innovative opera company in America, visit Motor City. Yuval Sharon has long used unconventional settings in unexpected ways, but now, as the artistic director of the Detroit Opera, he is breaking new ground. Lauded for past projects such as his reverse chronological staging of Puccini’s La Bohème, Sharon in July premiered a high-tech reimagining of a Wagner opera. Onstage action blended with computer animations with the help of green-screen tech. And of course: although the staging debuted in Los Angeles, it soon headed home to Michigan.
