To see bodies touching is fairly usual in dance duos, but in Diane Frank and Deborah Riley's "Overlap," which they performed at Dance Project this weekend, the two women were seldom apart. For almost an hour they explored the possibilities of moving together or resting in a space shaped partly by each other's contours. What was achieved had unusual intimacy, and suggested the contact of acrobats as well as of lovers.

Both women were dressed as gymnasts. At first, they stood back to back. Soon, the ways in which the two touched were varied, but the motion material was always athietic. That the sole sounds were of their breathing and impacts with the floor intensified the impression of a sports instead of dance event. But this objective atmosphere changed when the two dropped to rest together.

Gradually, subjectivity became part of the movement as well as the pauses, and then Frank and Riley rested less. They also quickened their pace as the hour progressed. While it was a feat to perform for such a time span, their inventiveness with overlapping bodies didn't quite justify the duration, nor did their contact's human qualities intensify toward the duet's end.
