Book excerpt: Edited by Yvonne Rainer, this selection of texts and images by Rainer and various authors offers a retrospective portrait of her work, focusing on some of her most notable performances and projects from both the late 1960s (?Trio A?, ?The Mind Is a Muscle?) and since her return to dance with the White Oak Dance Project in 2000. Rainer is known for her challengingly experimental and sometimes minimalist work as a dancer, choreographer, and filmmaker, which spearheaded the rise of postmodern dance. An essay by Rainer frames things from the perspective of an aging dancer who is aware of her physical limitations. With a conversation between Rainer and dancer Trisha Brown.
