Each year for the past decade, the French vocal and instrumental ensemble Les Arts Florissants has visited the Brooklyn Academy of Music. In that time, three of their productions stand out as particularly significant: Jean-Baptiste Lully's Atys (1989 and 1992), Marc-Antoine Charpentier's Medée (1994) and Hippolyte et Aricie by Jean-Philippe Rameau (1997). This trilogy of landmarks in the history of French opera was presented in fully staged productions conceived by stage director Jean-Marie Villegier and conductor William Christie.
