Trisha Brown is the most widely acclaimed choreographer to emerge from the postmodern era. As a member of New York's Judson Dance Theater in the 1960s she explored the function and content of human motion. Her dancers appeared on the roofs of high rise buildings, running down house walls whilst suspended from ropes, defining gravity anew. Through dance, Brown investigates the fundamental characteristics of movement: gravity, weightlessness, duration, sequence, and repetition, as well as the interactions between art and life. She founded her own company in 1970 and has worked notably with artists such as Robert Rauschenberg, Donald Judd, Laurie Anderson and John Cage.
