Lohengrin is early, just after Tannhäuser in the cavalcade of Wagner’s masterpieces, with a swan-drawn Arthurian hero in thrall to the Grail and with its somewhat repetitious plot as two nasty customers attempt to destroy the hero and his ladylove Elsa. Opera Australia’s production of Lohengrin with Jonas Kaufmann exhibits the spectacular vocal skills and consummate artistry of the man who is billed as the greatest mid-career tenor in the world and that is enough to justify the price of the tickets which reach into hundreds of dollars.
