IMPROVISATIONS Unlimited, one of the area's most consistently creative dance companies, will present recent and more seasoned work this weekend.

The eight-year-old, eight-member troupe in residence at the University of Maryland excels at that spontaneous, fearless form known as improvisation. Under the astute direction of Meriam Rosen, the troupe begins each performance with short movement sequences created on the spot, with Rosen's oral cues serving as take-off points.

The more formal part of the program will include three very different pieces: Kei Takei's "Flower Field," which had its premier several months back, is a dance of endurance that places its performers in what appears to be an agrarian society, and has them laboring, fighting, planting and surviving.

Jerry Pearson's "Zen Exercises for Limbs and Pins" is a far more lighthearted affair. The five performers enact a wonderful, rhythmic group ritual involving plastic bottles with wooden sticks stuck in their necks, and go on to use these mundane but magical props as both partners and toys.

The third piece -- Don Redlich's "Where Now, When Now?" -- uses pedestrian movement, cardboard crates, piles of newspapers and a multi-layered score by Luciano Berio to create a picture of a society gone totally berserk.

IMPROVISATIONS UNLIMITED -- Friday and Saturday at 8 p.m., George Washington University's Building K Theater, 23rd and K streets NW. Tickets, $7; students and seniors, $5. Call 676-6577.
