Some choreographers are asked about using nudity onstage, and their answers are great and interesting to read.
"In this day and age, when the naked body is constantly used in a sexualized or violent way, contemporary art and dance are some of the few places where we can still encounter it in a different, more neutral form.

You don’t have a lot of opportunities to compare yourself to other bodies, and you can recognize yourself and your scars in others. I admire people who use the naked body to make a statement about humanity." — Sidi Larbi Cherkaoui
