Simone Forti (born 1935), is an American Italian Postmodern artist, dancer, choreographer, and writer.
 Since the 1950's, Forti has exhibited, performed, and taught workshops all over the world, including performances at the Louvre in Paris, the Museum of Modern Art in New York, and the J. Paul Getty Museum in Los Angeles.
 Her innovations in Postmodern dance, including her seminal 1961 body of work, "Dance Constructions", along with her contribution to the early Fluxus movement, have influenced many notable artists, including dancer/artist Yvonne Rainer and the Judson Dance Theater in New York.
 Forti first apprenticed with Anna Halprin in the 1950s and has since worked alongside artists and composers Nam June Paik, Steve Paxton, La Monte Young, Trisha Brown, Charlemagne Palestine, Peter Van Riper, Dan Graham, Yoshi Wada, and Robert Morris, among many others.
 Forti's published books include "Handbook in Motion" (1974, The Press of the Nova Scotia College of Art and Design), "Angel" (1978, self-published), and "Oh Tongue" (2003, Beyond Baroque Foundation, ed.
 Fred Dewey).
 She is currently represented by The Box L.A. in Los Angeles, CA, and has works in the permanent collections of the Museum of Modern Art (MOMA) in New York, the Stedelijk Museum in Amsterdam, the Generali Foundation in Vienna, the Whitney Museum of American Art in New York, and the Moderna Museet in Stockholm.
The Grand Union was an improvisational dance group based in New York City from 1970 to 1976.
 It grew out of Yvonne Rainer dance company, and her piece "Continuous Project - Altered Daily".
 Rainer's sole authority as choreographer began to slip in early 1970 when the dancers, at her invitation, began to bring in their own materials for the piece.
 By late 1970, new members had joined the group and the materials were improvised to a much greater extent.
 The company, which was still often billed as "Yvonne Rainer and Dancers" in the beginning, chose "The Grand Union" as a name to avoid any obvious associations with dance in order to inoculate themselves against charges that what they were doing was not properly "dance".
 To avoid problems with the supermarket chain of the same name, the group used the legal name "Rio Grand Union".

Steve Paxton (born 1939 in Phoenix, Arizona) is an experimental dancer and choreographer.
