Up-and-coming choreographer Liam Scarlett is quickly becoming a household name across the pond. The deeply musical ballets he has made for The Royal, where he’s also a member of the corps de ballet, have earned raves from the London press. Thanks to Edward Villella, Scarlett is about to get a toehold over here, too: His first ballet for an American company premieres this January at Villella’s Miami City Ballet.
