The richness of the musical and dramatic material in Henry Purcell's hour-long 1689 opera Dido and Aeneas has inspired directors and opera companies to try all kinds of alternative stagings. Rarely have any been as successful as this mix of ballet and opera conceived by director Wayne McGregor for La Scala in 2006, and recorded in high-definition at the Royal Opera House, Covent Garden, in April. The music is superb, led by a fabulous performance by English mezzo Sarah Connolly as Dido. Christopher Hogwood crisply leads the Orchestra of the Age of Enlightenment. The action on stage is shadowed by 12 members of the Royal Ballet. Music and movement are always in perfect sync, both emotionally and physically. The sets are minimal, further putting the emphasis on the people. The main extra is a 10-minute interview with the engaging, 39-year-old McGregor, a rare example of a successful dance-opera crossover artist.
