Jerome Robbins created “Dances at a Gathering” — recognized as a masterpiece by many — to work on many different levels. It is pretty and joyous as well as technically impressive, with awe-inspiring moments of acrobatics sparingly sprinkled throughout.

Helge Tomasson’s choice of casting was a slight surprise to me, as it resulted in an opening performance of more exuberance than I have sometimes come to expect of this company’s performance of this Robbins classic.

The performances were effective and fairly even throughout, with Yuan Yuan Tan perhaps shining through a tad more than the others.
