i have seen this before but i agree with you that it is simply stunning. I have watched quite a few of these while studying Artaud to bring me a little more inspiration. Im glad you posted this for others to see.
I have seen "Alagria" before, it came to london not so long ago, and me and my class mate where putting on a simlar project (only not as glamorous due to our similar love for all things "Poor Theatre") so using some of the same atributes of Cirque. Ofcourse it would be nowhere near as professional were only students directing students - Artaud was the basis, the script was the back bone and the circusesq expressionistic way of viewing the production was infact the flesh. all in all incase you wondered A's all around. (Ha! to everyone else who laughed and did Naturalism.)
by the way, have you seen any of the other shows they have done such as..."Dralion" and "Varekai"? (they are the only ones that pop to mind due to our reasurch)
