Twenty-five years since acid house and Ecstasy revolutionized pop culture, Simon Reynolds's landmark rave history Energy Flash has been expanded and updated to cover twenty-first-century developments like dubstep and EDM's recent takeover of America. A longtime writer on the music beat, Reynolds started watching-and partaking in-the rave scene early on, observing firsthand ecstasy’s sense-heightening and serotonin-surging effects on the music and the scene. In telling the story, Reynolds goes way beyond straight music history, mixing social history, interviews with participants and scene-makers, and his own analysis of the sounds with the names of key places, tracks, groups, scenes, and artists. He delves deep into the panoply of rave-worthy drugs and proper rave attitude and etiquette, exposing a nuanced musical phenomenon.
