As the original sound evolved in the late 1980s and early 1990s, it also diverged to such an extent that a wide spectrum of stylistically distinct music was being referred to as techno. This ranged from relatively pop oriented acts such as Moby to the distinctly anti-commercial sentiments of Underground Resistance. Derrick May’s experimentation on works such as Beyond the Dance (1989) and The Beginning (1990) were credited with taking techno “in dozens of new directions at once and having the kind of expansive impact John Coltrane had on Jazz”. The Birmingham-based label Network Records label was instrumental in introducing Detroit techno to British audiences. By the late 1980s and early 1990s, the original techno sound had garnered a large underground following in the United Kingdom, Germany, the Netherlands and Belgium. The growth of techno’s popularity in Europe between 1988 and 1992 was largely due to the emergence of the rave scene and a thriving club culture.
In America, apart from regional scenes in Detroit, New York City, and Chicago, interest was limited. Producers from Detroit, frustrated by the lack of opportunity in their home country, looked to Europe for their future livelihood. This first wave of Detroit expatriates was soon joined by a number of up-and-coming artists, the so-called “second wave”, including Carl Craig, Octave One, Jay Denham, Kenny Larkin, and Stacey Pullen, with UR’s Jeff Mills, Mike Banks, and Robert Hood pushing their own unique sound. A number of New York producers were also making an impression at this time, notably Frankie Bones, Lenny Dee, and Joey Beltram. In the same period, close to Detroit (Windsor, Ontario), Richie Hawtin, with business partner John Acquaviva, launched the influential imprint Plus 8 Records.
Developments in American-produced techno between 1990 and 1992 fueled the expansion and eventual divergence of techno in Europe, particularly in Germany. In Berlin, following the closure of a free party venue called Ufo, the club Tresor opened in 1991. The venue was for a time the standard bearer for techno and played host to many of the leading Detroit producers, some of whom relocated to Berlin. By 1993, as interest in techno in the UK club scene started to wane, Berlin was considered the unofficial techno capital of Europe.
Although eclipsed by Germany, Belgium was another focus of second-wave techno in this time period. The Ghent-based label R&S Records embraced harder-edged techno by “teenage prodigies” like Beltram and C.J. Bolland, releasing “tough, metallic tracks…with harsh, discordant synth lines that sounded like distressed Hoovers,” according to one music journalist.
