“Four Walls” was a dance-play written, directed and choreographed by Merce Cunningham, with a piano score by John Cage. Arch Lauterer designed the set and costumes, and collaborated on the direction. The text was a drama about a dysfunctional family with a cast of characters that included a weak but loving mother, a silent father, their rebellious son (“the Boy” played by Cunningham) and daughter, the daughter’s fiancé, a speaking chorus of “Six Nearpeople” and a dancing chorus of “Six Mad-Ones.” Cunningham rehearsed and performed the work during a six-week teaching engagement at the Perry-Mansfield Workshop, a summer arts camp. It was shown in its entirety only once. Dances excerpted from the work were presented on a few occasions, including a solo arrangement given the title “Soliloquy.”
