I have probably spelled the German incorrectly; that's "ballet of dead women," which is from Heiner Muller's
Hamletmaschine, and which I used also as the title of a piece which was part of my solo show years ago, "Death or Serious Injury Can Occur."
I'm currently embarking on the adaptation of a ballet (indeed, a ballet of dead women),
Giselle. I am doing a buttload of research; for instance, I'm watching
La Sylphide, known as the first Romantic ballet (I guess
Giselle is known as the second Romantic ballet - but it's also the most famous Romantic ballet).
But all's not fun and games and watching men and women dance on point.
