Short answers, pulled from the story.
Electronic dance music began in the 1960s with pioneers like King Tubby using studio mixing boards to create dub music. This era laid the groundwork for a global phenomenon through the experimental deconstructions of reggae tracks and the use of equipment like the Roland Space Echo in the 1970s.
The Roland TR-808 drum machine played a crucial role in the evolution of electro and house music by providing synthesized programmed drum beats that defined the genre. This device became a fundamental element of futuristic sound and influenced subgenres including Miami bass and Detroit techno after its introduction to clubs in 1980 and 1982.
Jungle and drum and bass emerged from the underground rave scene in the late 1980s and gained mainstream popularity by 1994 through the combination of sampled syncopated beats with samples from genres like raggamuffin sound and dancehall. By 1995, some jungle producers moved away from the ragga-influenced style to create what became collectively labelled as drum and bass.
Major festivals like the 2014 Ultra Music Festival brought 165,000 attendees and over 223 million dollars to the Miami/South Florida region's economy. The 2015 EDC Las Vegas event boosted the Clark County economy by 350.3 million dollars with over 405,000 attendees across three days.
Producers and DJs including Carl Cox and Steve Lawler raised concerns that the perceived over-commercialization of dance music had impacted the art of DJing and led to a homogenized sound. The American popular EDM market started to wane in 2016 when some producers began to diversify beyond the big room sound with releases like The Death of EDM.
The production of electronic dance music has evolved from hardware-based studios to digital audio workstations that allow producers to create entire tracks on a laptop. This shift has democratized the creation of electronic music through low-cost accessible software and equipment while also leading to the phenomenon of ghost production.
