What music genre formed during the 1980's and early 1990's  and was crucially incluenced by a band founded in 1981 by Beate Bartel and Chrislo Haas?
Liaisons Dangereuses (band) Liaisons Dangereuses was founded by Beate Bartel (Mania D, Einstürzende Neubauten) and Chrislo Haas (Deutsch Amerikanische Freundschaft) together with vocalist Krishna Goineau in 1981. As a part of the Neue Deutsche Welle scene (especially "electropunk" ) in Germany they pioneered electronic body music. After recording four ten-minute cassettes, they released their sole album in 1981. The self-titled album was mixed at Conny Plank's studio in Köln. The group made several live appearances throughout 1981 and 1982 and were occasionally joined by Anita Lane (Nick Cave and the Bad Seeds) and Hideto Sasaki. The album carried the single "Los Niños del Parque" which became an underground hit and has been cited by many prominent Chicago house and Detroit techno DJ's as a crucial influence.
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.
