In the words of the prestigious German weekly 'Die Zeit,' the stage production of Wagner's 'Rheingold' and 'Walküre' by La Fura dels Baus 'quite possibly shows us the path that musical theater will be taking in the future.' There's no doubt about it: the Catalan city of Valencia is setting new accents in 21st-century opera not only with its spectacular new theater designed by Santiago Calatrava, but also with its visually transfixing production of Wagner's 'Ring' staged by Carlus Padrissa and his theater group La Fura dels Baus.

It has been a long time since the events of Das Rheingold. Wotan has fathered nine Valkyries, warrior women who bring dead heroes to Valhalla (the castle of the Gods). Richard Wagner's dream of a Gesamkuntswerk becomes reality through La Fura dels Baus' visual fantasy and blending of video technology, lighting and props (often formed of human beings): Their 30 computer projections and organic structures built of athletic performers that recall Cirque du Soleil are predestined for Wagner's visionary expressive world.

In the forest, the animals and insects are playing and dancing. The Forester enters and lies down against a tree for a nap. A curious Vixen Cub inquisitively chases a frog right into the lap of the surprised forester who forcibly takes the vixen home as a pet. Time passes and we see the Vixen, now grown up into a young adult tied up in the forester's yard with the conservative old dachshund. Fed up with life in confinement, the vixen chews through her rope and runs off to freedom.

Directed by Ursel Hermann, this 2005 production of Mozart's last opera stars a remarkable cast with Susan Graham in the role of Sesto, Christoph Prégardien giving life to Tito and Catherine Naglestad embodying the ambitious Vitellia. Premiered in September 1791 for the coronation of Leopold II, King of Bohemia, La Clemenza di Tito celebrates the figure of the merciful sovereign

L'Opéra National de Paris' production of L'Amour des trois oranges must certainly be one of the most elaborate operatic presentations. It has a cast of gazillions, characters who fly, jugglers, fire-eaters, remarkably elaborate costumes, amazingly realistic props (those five-foot oranges are convincingly juicy and edible looking), a huge set, fireworks, and so on. In fact, at times, it looks more like a Cirque de Soleil show than something you'd see in an opera house. Director Gilbert Deflo's conception and William Orlandi's costumes and sets are rooted in commedia dell'arte, but the production is thoroughly eclectic, with allusions to a wonderfully weird assortment of styles and periods.
