Italo Disco is a very broad term, encompassing much of the disco music output in Europe during the 1980s. It is one of the world's first forms of completely electronic dance music that evolved during the late 1970s / early 1980s in Italy, Spain, Germany, and other parts of Europe. Italo Disco music has a distinct, futuristic and spacey sound, which was created using synthesizers, drum machines, and vocoders. The term, "Italo-disco" was marketed only in Europe in the early 1980s by a German record label ZYX Music.In North America, UK, and Australia, Italo-Disco was mostly an underground phenomenon that could only be heard at night clubs or through homemade DJ mixes. The entry of synthesizers and other electronic effects into the disco genre produced electronic dance music, including America's Hi-NRG and Europe's Space Disco. The latter received its name because of its odd synthetic sounds, sci-fi costumes, and space-related themes. Dancers and listeners experienced something new because the artists' use of new music-shaping technologies created the perception of being in a very large space and because of the discotheques' lighting displays. Italo Disco's influences were Italian producer Giorgio Moroder, French musician Didier Marouani, a couple of hits by the French drummer Cerrone, electropop (Telex, Devo, and Gary Numan), and the early Hi-NRG albums of San Francisco producer Patrick Cowley with such singers as Sylvester and Paul Parker.
