This ballet is the namesake of a 1997 Boris Eifman production that doubles as a biography of dancer Olga Spessivtseva (SPEH-siv-TSAY-vuh). Pressure from Nathalie Fitzjames resulted in the addition of this ballet's traditional “peasant pas de deux.” Lines of dancers enter from both sides of the stage (15[1])and hop towards each other en arabesque in a waltz from its ballet blanc second act that is performed by the followers of (*) Queen Myrtha. Carlotta Grisi (-5[1])became a (10[1])star after the premiere of this ballet, whose first act ends with a mad scene (10[1])prompted by Hilarion's revelation that the title character's suitor Loys (-5[1])is actually Duke Albrecht. For (-5[1])10 points, name this Romantic ballet composed by Adolphe Adam, whose title character's spirit is raised from her grave (10[2])by the Wilis (VEE-leez). ■END■
