They also have revived ballets no longer performed anywhere else. One of those is “Valses Nobles et Sentimentales,” from 1947, which had not been seen in decades when Barbieri and Webb brought it back in 2011. It is the opening ballet in the company’s sixth digital program, an hour-long triple bill devoted to Ashton. (The program is available through Wednesday, one day longer than planned, because of a technical glitch that delayed the digital release.)
“Valses Nobles” is set to Ravel’s suite of the same name. With its layered melodies and unsettling dissonances, the music suggests both a dreamy euphoria and a kind of foreboding. Just four years later, Balanchine would use the same suite to much darker effect in his own ballet “La Valse.”
