Robert Gottleib is unequivocal about New York City Ballet’s unleashing of a Boris Eifman Balanchine tribute: “Eifman’s Musagète may not be the worst ballet ever put on by New York City Ballet—the last 20 years have offered it lots of competition—but its premiere last Friday was without question the lowest point in the history of the company (and I’ve been following its fortunes since the beginning, in 1948).”
