A rave is a large party or festival with disc jockeys playing electronic music. Music played at raves include house, trance, techno, drum and bass, dubstep and other forms of electronic dance music (EDM). There is a lot of dancing. Raves also have laser light shows, projected images and other visual effects used to create a fantasy-like scene. Raves mostly developed from acid house music parties in the mid-to-late 1980s in England and Ibiza. From there, it quickly spread to mainland Europe and the United States.
