When Simone Forti moved from California to New York City in 1960, she brought with her the improvisational approach of Anna Halprin. As one of the first five students in Robert Dunn's John Cage–inspired composition course (that led to Judson Dance Theater), she was a magnet for two others in that class: Yvonne Rainer and Steve Paxton. This month the three reunite for Tea for Three, an evening of moving and talking at Danspace Project, Oct. 26–28. It's a chance to see how dance mavericks grow and change and mellow. Forti will also give "Body Mind World" workshops Oct. 19–20. danspaceproject.org.
