Boston Ballet’s 2017–2018 season concludes with La Sylphide, a program showcasing Danish choreographer August Bournonville’s romantic and tragic tale of La Sylphide and Bournonville Divertissements, a series of excerpts from his classic works. “La Sylphide is considered by many the epitome of Romantic ballet—with its timeless tale, storytelling through mime, and ethereal dancing. Paired with rarely-performed Bournonville Divertissements, this program is an excellent showcase of the Bournonville style of dancing,” said Artistic Director Mikko Nissinen.
