American Ballet Theatre’s fall season has been brief, too brief to form a sense of the new director Susan Jaffe’s tastes and intentions. That will come in time. This fall, we got a roundup of some of the company’s past repertory, from Balanchine’s 1941 “Ballet Imperial” to last year’s “Single Eye,” by the San Francisco-based Alonzo King. In the final program of the season, which ended on Oct. 29, the latter was paired with Alexei Ratmansky’s 2009 “On the Dnipro,” the first work for the company by its former choreographer in residence. Between the two, almost as a palate cleanser, came a short pas de deux by Gemma Bond, set to a rapturous aria from Gustave Charpentier’s opera “Louise.” I caught two performances, on Oct. 27 and at the Oct. 29 matinee.
