FOR ANYONE interested in art, performance, boundary-breaking and free- flowing discussion, the Dance Exchange's "Evening of Exchange" series is a special opportunity. On any given program, you can see and hear changing combinations of dance, theater, music, poetry and film; listen to historians, critics and the artists expound on the works; and -- if the spirit moves you -- ask questions or contribute your own thoughts. And you don't have to pay a cent.

The series opens its fourth season Friday night with "New Voices of Women in the Arts." The participants, from this city and New York, work in different media and yet their "voices" share a direct, compassionate and often humorous tone.

Choreographer Blondell Cummings, a performer of great strength and daring, will perform excerpts from her just-premiered "The Art of War/9 Situations," which is based on the writings of the Chinese philosopher Sun Tsu. The character of a nun figures prominently in the piece. Filmmaker and poet Michelle Parkerson will screen sections of her documentary "Gotta Make This Journey: Sweet Honey in the Rock," and read from her recently published poetry collection "Waiting Rooms." Finally, the theatrical collective Horizons will perform parts of "Women's Work," a rousing dramatic presentation based on oral histories gathered during the Depression by participants in the Federal Writers' Project.

NEW VOICES OF WOMEN IN THE ARTS/EVENING OF EXCHANGE -- Friday at 8, Hand Chapel, Mount Vernon College, 2100 Foxhall Road NW. Admission free. 232- 0833.
