Under Dima Slobodeniouk, the orchestra played works by Holst and Ligeti and, for the first time, Julia Perry’s somber “Stabat Mater.”

Her high notes emerging like shafts of sunlight, Davidsen is playing the title role in Janacek’s “Jenufa” at the struggling Lyric Opera of Chicago.

Starring Ailyn Pérez, Daniel Catán’s heavily perfumed “Florencia en el Amazonas,” from 1996, is the company’s first work by a Latin American composer.

The group, which celebrated its birthday on Friday at Carnegie Hall, changed music with its open-eared and open-minded approach.

Anthony, Christopher and Thulani Davis collaborated on “X: The Life and Times of Malcolm X,” which has its Metropolitan Opera premiere on Friday.

Jeanine Tesori and George Brant’s “Grounded,” which Washington National Opera premiered on Saturday, is headed to the Metropolitan Opera next year.

Alexandre Kantorow made his Carnegie Hall recital debut after winning both the International Tchaikovsky Competition and the Gilmore Artist Award.

A gift from a board member recently paid for the company to rebuild sets for Franco Zeffirelli’s deathless 1981 production of Puccini’s classic.
