Extreme yodelling at opera house

Extreme yodelling and karaoke are coming to the home of heavyweight opera this summer in a series of radical performances.

The Swiss singer Christian Zehnder will deliver a Royal Opera House set described as a mixture of "throat singing, opera and extreme yodelling" – a singing style performed at a higher volume and with more exaggerated vocal movements.

The performance is the latest attempt to bring opera to a wider audience, following a work based on the troubled life of former Playboy model Anna Nicole Smith, and OperaShots, a triple bill of modern operas with contemporary themes.
