Anne McElvoy talks to award-winning choreographer, dancer, director and designer Wayne McGregor as he prepares to open his productions of Handel's Acis and Galatea and Purcell's Dido and Aeneas at the Royal Opera House, Covent Garden. In this much-anticipated double-bill, both productions unite the performing companies at Covent Garden, with dancers from the Royal Ballet performing alongside aritsts from the Royal Opera, including singing stars Sarah Connolly and Danielle de Niese. McGregor discusses combining the disciplines of opera and dance, the challenges of bringing contemporary aesthetics to traditional ballet and about the continuing power of the music of arguably two of the greatest composers ever to work in London.
