MONTCLAIR, N.J. — The choreographer Elizabeth Streb has found herself in foreign territory. First, she is collaborating, which is not her usual way of making art. And in teaming up with Anne Bogart, a director of the theater group SITI Company, she has something else to contend with: words.

“I don’t really work with words,” she said between rehearsals at the Alexander Kasser Theater at Montclair State University here. “I don’t know how to do that.”

Ms. Streb has built a repertory and a reputation creating action works that strive to defy gravity. Give her and her company, Streb Extreme Action, a platform 30 feet in the air to leap off, a sheet of plexiglass to crash into, or a mat to land on, face forward, with a splat, and they’re right at home.

But in “Falling & Loving,” which begins on Tuesday as part of the series Peak Performances, Ms. Streb isn't the only one in charge. She has teamed with Ms. Bogart to direct the production, which features six SITI actors and six Streb dancers, who do not speak.
