For Starters, watch this video for an idea of what Butoh is. Butoh is the art of body-play/dancing while dawning white make up.
This video shows the Master of Butoh doing his last performance in the style known as Weakened Butoh. The Act of performing weakened butoh was banned from showcase for 30 years after this performance. The ban was lifted in 2003.
youtube has plenty of other videos of butoh for those who are interested. Just thought it would be something the community would have an interest in. At least some of us!
