Italy contributed to the development of disco and electronic music, with Italo disco, known for its futuristic sound and prominent use of synthesisers and drum machines, being one of the earliest electronic dance genres, as well as European forms of disco aside from Euro disco (which later went on to influence several genres such as Eurodance and Nu-disco). By the latter half of the 1990s, a subgenre of Eurodance known as Italo dance emerged. Taking influences from Italo disco and Italo house, Italo dance generally included synthesizer riffs, a melodic sound, and the usage of vocoders. Notable Italian DJs and remixers include Gabry Ponte (member of the group Eiffel 65), Benny Benassi, Gigi D'Agostino, and the trio Tacabro.
