The rest of A.B.T.’s three-week season is a hodgepodge of old and new. One program offers three ballets from the company’s earliest years, including Antony Tudor’s 1938 “Gala Performance,” a spoof of ballet mannerisms and ballerina airs. Another looks back at Twyla Tharp’s long association with the company, which began in 1976 with “Push Comes to Shove,” a tour de force of vaudevillian humor and bravura that she created for the recently arrived Mikhail Baryshnikov. (It will be danced by two of the company’s current crop of virtuosos, Isaac Hernandez and Jake Roxander.) Yet another program combines a new work by the Brazilian-born Juliano Nunes with one of the most powerful works created for the company in the past decade, Alexei Ratmansky’s “Serenade After Plato’s Symposium.”—Marina HarssAbout TownIndie Rock
