Powerful Verdi

Welsh National Opera’s Don Carlos is a magnificent achievement, despite a fair number of more or less serious shortcomings. It establishes, at any rate, that this is by far the most probing and powerful of Verdi’s operas, while being, whichever rich selection of scenes is chosen, far from perfect. Despite its Wagnerian length, almost four hours of music at Cardiff, there is a bewildering number of loose ends and implausibilities, as well as a failure to bring the figure of Carlos himself into focus.
