The FirstWorks Festival concludes Saturday with gravity-defying illusions by Momix at the Providence Performing Arts Center.

Momix returns, and it brings back its best: Best of Momix.

This Saturday’s show at the Providence Performing Arts Center wraps up the five-weekend FirstWorks Festival, and celebrates 25 years of graceful and artful oddity: Momix.

The internationally known performance troupe, based in Washington, Conn., is composed of dancers and acrobats, although they refer to themselves as movement illusionists, moving and joining their bodies in unusual and fantastical ways.

Normally the company, under the artistic direction of Moses Pendleton, its founder, presents thematic shows. But the theme of this 90-minute show is, as advertised, the best of Momix, a sort of sampler of the company’s 25-year history, presenting 20 works drawn from a repertoire of more than 100.

You may see people swinging in an airborne choreography, or crawling on the floor like big bugs. If you haven’t seen Momix before, it’s probably like nothing you’ve seen.

The Best of Momix is Saturday at 8 p.m. in PPAC, 220 Weybosset St., Providence. For tickets, $28 to $48, call (401) 421-2787 or visit www.ppacri.org.
