An impressive open air set built over an alpine lake in Austria is about to host a grand production of the opera Carmen. The design features an enormous deck of cards which is thrown in the air by two twenty-metre high giant hands, coming out of the water. Carmen will open the 72nd Bregenz festival. Carmen. It’s Georges Bizet’s most famous opera – a story of love and passion that always draws crowds, thanks to its delightful arias such as Habanera or the Toreador song. But here in Bregenz, on the Austrian shores of Lake Constance, the true star is the stage. It sits on the water, with Germany and Switzerland in the background.
