Interesting casting for the ABT Sylvia Thursday night. Gillian Murphy was injured, replaced by not one dancer but three separate casts: Isabella Boylston and Marcelo Gomes as Sylvia and Aminta, respectively in Act I; Maria Kochetkova in Act II; and Hee Seo and Roberto Bolle in Act III. Strange that Isabella and Marcelo did not dance the entire performance. The mix and match performance was somewhat disjointed from act to act, but it was a special evening to see a number of principal dancers perform, particularly the always great Roberto Bolle. Check for my review of the Thursday and Saturday Sylvia performances on Sunday.
