Nothing is certain in "Noir," Noémie Lafrance's latest celebration of New York and its possibilities for site-specific dance.

You could call Mr. Jasperse's new "just two dancers" a site-specific dance, created as it was for the intimate black-box stage of Dance Theater Workshop.

A tour that incorporates site-specific dances, music and history.

Inspired by the possibilities of climbing and rappelling, the choreography draws on aerial, vertical and horizontal movement to craft dances, many site-specific.

Lafrance's site-specific dances and installations use an existing indoors or outdoors public site or piece of urban architecture as the setting and inspiration for the performance.

While the troupe performed improvisations and site-specific dances there, several members of the company presented photographs, poetry and videos they had created.

Since then, Jennifer Monson has followed the migration patterns of gray whales, ospreys, ducks and geese, presenting free, outdoor site-specific dances, workshops and panels on conservation along the way.

Larry Keigwin - like Mr. O'Connor, a newcomer to site-specific dance - said he had originally envisioned a pastoral setting and sought out images of animals for inspiration.

The choreographic team known as Eiko & Koma, who have long experience in site-specific dance, appeared more nonchalant.

New York has had a long tradition of site-specific dance.
