Watch Tosca (2019) : Full Movie Online Free To open its 2019-2020 season, La Scala in Milan has chosen Tosca, in a new production directed by Davide Livermore. The production is part of the rediscovery of Italian opera led by Riccardo Chailly, the conductor of the production and music director of La Scala. He has chosen the original version of Tosca, as created by Puccini in Rome in January 1900, which included eight "additional musical inserts" that were removed from the work after its second performance in Turin in February 1900 and will now be rediscovered for the first time on December 7 at La Scala.
