A couple of days ago the London Evening Standard had a leading article in the Arts section by Norman Lebrecht on how Monica Mason has appointed Wayne Macgregor (of Random Dance Company) as the Royal Ballet's principal choreographer. This is remarkable news as the company has not had a principal choreographer since the death of Kenneth MacMillan. And Macgregor will only be the 3rd such in the company's 75 year history (the first was founder Ninette de Valois, the second Frederick Ashton and MacMillan was the 3rd). David Bintley also had a post at the Royal Ballet but I'm not sure what that was.
But Macgregor is an experimental choreographer who works on abstract pieces and does not create the narrative ballets which have been a significant part of the Royal Ballet's life. Lebrecht's article was balanced and illuminating and you can read it here.
