In 1975, artist Senga Nengudi began a series of sculptures, entitled R.S.V.P., which evoke the elasticity and durability of the human body. Made of everyday materials, such as pantyhose and sand, the works invite viewers to not only respond but to engage with them physically. Stretched and twisted, knotted and looped, the works occupy their space in the gallery much as a figure does—by projecting outward and reaching into the space of the viewer in unexpected ways. Improvisional Gestures includes works from the 1970s to the present, and is the first museum presentation to examine these sculptures together and in such depth. Senga Nengudi: Improvisional Gestures is organized by the Museum of Contemporary Art Denver and the University of Colorado, Colorado Springs Gallery of Contemporary Art.
