Les Boréades: Director Robert Carsen and his creative team flood the stage with summer blossoms, drifts of autumn leaves, winter snows and thunderous spring storms.

This mythical tale of a young queen, Alphise, determined to abdicate rather than contemplate an enforced marriage to a descendant of Boreas, is nothing less than highly-charged.
