Rave music Rave music may either refer to the late 1980s/early 1990s genres of house, breakbeat, acid house, techno and hardcore techno, which were the first genres of music to be played at rave parties, or to any other genre of electronic dance music (EDM) that may be played at a rave. The genre "rave", also known as hardcore by early ravers, first appeared amongst the UK "acid" movement during the late 1980s at warehouse parties and other underground venues, as well as on UK pirate radio stations. The genre would develop into oldschool hardcore, which lead onto newer forms of rave music such as drum and bass and 2-step, as well as other hardcore techno genres, such as gabber, hardstyle and happy hardcore. Rave music is usually presented in a DJ mix set, although live performances are not uncommon.
