Book excerpt: Born from extensive international research, Global Tribe documents a little understood global dance culture that has mushroomed all over the world since its beginnings in diverse psychedelic music scenes flourishing in Goa, India, in the 1970s and 1980s. From small parties to major international events such as Portugal's Boom Festival, the paramount expression of this movement has been the festival. Via first-hand accounts of the scenes, festivals and music of psychedelic trance (psytrance) in Australia, Israel, Italy, the UK, the US, Germany, Turkey and other places, the author explores this transnational movement with attention to its diverse aesthetic roots, national translations and internal controversies. As a thoroughly engaging multi-sited ethnography and an intimate examination of the digital, chemical, cyber and media assemblage of psytrance, Global Tribe studies the integrated role of technology and spirituality in the formation of this visionary arts movement. The book demonstrates how the event-cultures of psytrance accommodate rites of risk and consciousness, a complex circumstance demanding revision of existing approaches to ritual, music and culture.
