This piece was done for a dance performance by Hajime Fujita, a japanese contemporary dancer that I meet in Porto, in 2009, during Future Places Festival (although he was using the same space, Maus Hábitos in Porto, he is unrelated to the festival as far has I know). He used it in a performance in the 3rd Encounter of Performative Arts promoted by Contagiarte in 2009. I've also uploaded his room information brief.
I've used several sound recordings I had done in Trás-os-Montes, Lisbon and Germany.
