de Mille

But it’s also a throwback to an older, neglected mode of integrating dance into a musical, the tradition that Agnes de Mille inaugurated with shows like “Oklahoma!” and “Carousel” in the 1940s.

But when word spread that Collins was making her Broadway debut in a show staged by Agnes de Mille, Rivera’s mind started to shift.

The festivities include Graham classics and a re-envisioned “Rodeo” by Agnes de Mille.

The celebration begins Sept. 30 at the Soraya, with performances of Graham classics “Appalachian Spring,” “Dark Meadow” and “Maple Leaf Rag” alongside a re-orchestrated production of Agnes de Mille’s 1942 work “Rodeo.”

Along with Graham and de Mille, the long list of those who taught and performed there includes Doris Humphrey, who directed its dance center in the 1940s.
