techno,electronic dance music that began in theUnited States in the 1980s and became globally popular in the 1990s. With its glacialsynthesizer melodies and brisk machine rhythms, techno was a product of the fascination of middle-class African-Americanyouths inDetroit,Michigan, for European electronic dance music.

Influenced byKraftwerk’s Teutonic electro-pop and Alvin Toffler’s concept of “techno rebels,” a clique of deejay-producers—Derrick May, Juan Atkins, and Kevin Saunderson—began drawing attention to their innovativemusic in 1985. Crossing the Atlantic as an adjunct to Chicagohouse music, their early tracks—Rythim Is Rythim’s “Strings of Life,” Model 500’s “No UFOs,” and Inner City’s “Good Life”—incited pandemonium on Europe’s dance floors. Unlike house, Detroit techno was primarily all-instrumental, and its beats were more complex than thedisco-derived, four-to-the-floor kick-drum that underpinned house.

As the Detroit sound became a mainstay of theEuropean rave scene (the neo-psychedelic subculture based around ecstasy-fueled all-night dance parties), white producers took the music in a harder-edged direction, replacing its dreamy elegance with aggressive riffs and druggy sample textures. Pioneered by Joey Beltram fromNew York City, Belgian artists such as 80 Aum and Human Resource, and second-wave Detroit labels Underground Resistance and +8, this new brand of techno was called hardcore, signifying both its militant attitude and ecstasy-driven hedonism. Meanwhile, British styles such as the minimalist bleep-and-bass and breakbeat hardcore were bringinghip-hop influences into the mix. By the mid-1990s, techno had fragmented intomyriad subgenres, the most important being trance (characterized by metronomic beats and cosmic melodies), electronica (atmospheric experimentalism designed for album-length home listening), jungle (based around sped-up hip-hop breakbeats and floor-quakingreggae bass), and gabba (an ultrafast furor closer toheavy metal than dance music). Although puristconnoisseurs pined for the lighter touch of the Detroit originators and their inheritors Carl Craig and Jeff Mills, a rowdy, rock-and-roll mutant of techno invaded the American mainstream in 1997, with the success of albums by theProdigy and the Chemical Brothers.
