Two historic performances embody dancing luminary Martha Graham's depth as a trailblazing choreographer and entertainer. The 1961 production of "Night Journey" retells the story of the fabled Oedipus, while "Appalachian Spring" -- featuring composer Aaron Copland's original score -- honors the American pioneer. Also included is the documentary A Dancer's World, which goes behind the scenes to Graham's dressing room as she prepares for a show.
