Book excerpt: This book explores dancing from the 1960s to the 1980s; though this period covers only twenty years, the changes during it were seismic. Nevertheless continuities can be found, and those are what this book examines. In dancing, it answers how we moved from the self-control that formed the basis for ballroom dancing, to ecstatic rave dancing. In terms of music, it answers how we moved from the beat groups to electronic dance music. In terms of youth, it answers how we moved from youth culture to club culture.
