http://www.youtube.com/watch?v=XR0HncPEzNgI posted the above link on a flamenco board where someone had started a thread on dystonia, asking initially about Farias.
The moderator chipped in saying he reckoned the video was a fake - that the lighting, settings and the person's clothes were all the same and therefore they were probably shot at the same time with the dystonia symptoms faked.
I pointed out that there were several on this board who would argue with that and asked him whether he thought all the other Fabra videos were faked too. No answer yet.
