Zurich Ballet is certainly adaptable. Also presently dancing William Forsythe’s Artefact, it says a great deal that they can not only turn to La Sylphide, the most enduring of Romantic ballets, but dance it with such conviction and in such authentic style.

Richard Llewellyn’s famous novel How Green Was My Valley certainly sets some choreographic challenges. It cannot be easy to translate such detailed events and complex relationships covering a lengthy period of time into a successful ballet. Yet Darius James, artistic director of  Independent Ballet Wales, has done a cracking job in his latest work for his bright company.
