The dance is fascinating. From Lesley Eneanora Boyce-Wilkinson's essay on butoh.de:
Butoh disregards all notions of sophistication and the symbological referencing. It does not seek idealised form or harmonically choreographed patterning, but rather embraces the grotesque, the ungainly, the raw, non-aesthetically encoded body. Butoh gropes beneath the overlay of socialisation and cultural authoritarianism for what the critic Ichikawa miyabi called "the body that has been robbed" and attempts to restore a wild inner flame in the heart of darkness.
The forms put me in mind of certain of Mapplethorpe's images (and many thanks to NMB for introducing me to these) -
The spectacle (the gaze)
and the file cabinet
