I searched CD to see if this topic has been posted before, but came up with nothing, about the best Web site I have ever seen, on any subject, in terms of content, usability, and presentation.
Visit the dressing room locker of Martha Graham dancer Jordy Kandinsky to view snippets of Appalachian spring, Lamantations, and other performances; hear music recordings; read Jordy's journal; her rehearsal schedule; read historical articles about Martha Graham, etc., etc. Included are resources for dance teachers.
The delivery is the most clever design and use of technology I've seen on the Web. A delight. http://www.artsedge.kennedy-center.org/marthagraham/
