Ballerina in a Whirlpool is a catalog of an exhibition featuring Isa Genzken, Richard Jackson, Roman Signer and Diana Thater. Despite the exhibited artists' various American or European backgrounds, their varied media and lines of inquiry, their disparate works share one formal motif–the circle, circular pattern, or rotating movement. Whether this movement is real or implied, possible, inherent in the work, or performed by the viewer in space, it brings together this fascinating group of installation works for closer examination.
