Martha Graham's achievement was the beginning of American modern dance as we know it today. Others had pointed the way - Isadora Duncan and Graham's own teacher Ruth St Denis - but it was Graham in the 1930s who wrote the maps of possibility for drama and depth in movement which others have been exploring ever since. Returning to London after a 20- year gap, her company brings a collection of its late founder's early work, including the landmark ballet which Aaron Copeland wrote for her, Appalachian Spring, evoking the courage of the pioneers who opened up a new land. Equally characteristic of Graham's originality is Errand into the Maze, where Greek myth forms the basis of psychological insight into a woman's hopes and fears about sex. This programme shows a pioneer of dance at her most powerful.
