This is the organizational approach to Festival Culture that I referred to in the "Electronic Awakening" post. Below is their introductory video, but I would encourage anyone interested in the Festival phenomenon to at least look through their video collection. Each one focuses on some aspect of Festival Culture; art work, community creation, music, etc. They are very well produced and visually impressive, as is their website, but the content is really quite good as well.
I am developing my own approach to Transformational Festival culture as I integrate this phenomenon into the work that began with my fieldwork at El Rocio.
