Jewels at the Royal Opera House, London Balanchine’s Crowning Glory Exquisite contrasts of mood & music shine through in George Balanchine’s fabulous gem of a ballet. The French romantic music of Faur provides the impetus for the subtlety & lyricism of ‘ Emeralds’, while the fire of ‘ Rubies’ comes from Stravinsky & the jazz-age energy of New York. Grandeur & elegance complete the evening with the splendour of Imperial Russia & the peerless music of Tchaikovsky acting as the ‘ Diamonds’ in this ballet crown.
