For the first time the opera “Mosè” by Gioachino Rossini is on stage inside a Cathedral in a semi-scenic performance at the Duomo di Milano. The Veneranda Fabbrica del Duomo di Milano, in the wake of a centuries-old tradition of dialogue with the contemporary, chooses the most advanced technology to open up to the world and the public with an immediacy never achieved until now, including lights and colors effects that characterize the scenes of the show, with an evocative videomapping technique.
