Although Frederick Ashton is the genius on whom British ballet is based, it could have been Anthony Tudor who got the crucial job. In a few brilliant years in the 1930s, between them they produced a handful of masterpieces that have endured 70 years, and will surely endure further. Ashton was making larky, sophisticated modern entertainments such as Façade and Les Rendezvous when Tudor made two ballets that were shocking in their time, for exposing emotions never talked about and opening up a rich seam of ballet that is feverishly mined by today’s choreographers.”
