From its first publication in 1997, ALTERED STATE established itself as the definitive text on dance culture. This new edition sees Matthew Collin revisit many of his interviewees from the original book, with hindsight casting a fresh eye on the heady events of the second summer of love. ALTERED STATE re- examines the causes and contexts, ideologies and myths of Ecstasy culture, dramatising its euphoric narrative from peak experience to come down and aftermath, and shedding new light on the social history of the most spectacular youth movement of the twentieth century.
