Following Ashley Page’s Larina Waltz, a posh bit of partnering to establish that, yes, these dancers certainly can ballet, the other works all register loss and tribute. Jerome Robbins (West Side Story’s exacting creator) made Quiet City in 1986 in memory of a young dancer who had killed himself. Mournfully scored by Aaron Copland, it is led by Cuban dancer Alejandro Virelles, held high by two men who spin in his wake like attendant angels. A wonderfully elastic Virelles seems to grieve the world he leaves behind, taking one last leap to touch the sky before a trumpet plays like the last post.
