"This problem-oriented guide for police addresses the problems associated with rave parties. Rave parties - or, more simply, raves - are dance parties that feature fast-paced, repetitive electronic music and accompanying light shows. Raves are the focus of a youth-oriented subculture that blends music, art, and social ideals (e.g., peace, love, unity, respect, tolerance, happiness). The rave culture also entails the use of a range of licit and illicit drugs. This guide is an essential tool for law enforcement in developing responses to their local rave party problem."
