"I can't recommend this marvellous piece of work enough." --Irvine Welsh

Altered State--now updated--is the definitive text on ecstasy culture, using a cast of characters to track the origins of the scene through psychedelic subcults, underground gay discos, and the Balearic paradise of Ibiza. It examines the ideologies and myths, documenting the criminal underside to the blissed-out image, and shedding light on the social history of the most spectacular youth movement of the twentieth century.
