Improvisations Unlimited was a modern dance company based at the University of Maryland, College Park, from 1978-1992. Founded and directed by university dance professor Meriam Rosen, the company began with informal performances of improvised movement, but gradually introduced more structured choreography, though still within a largely improvisational framework. Improvisations Unlimited commissioned works by well-known choreographers and developed a repertoire of works and workshops, which they performed and conducted for a wide array of audiences, including dancers, children, older adults, and populations with special needs throughout the Washington, D.C.-area and the Eastern Seaboard.
