Intelligent dance music

Intelligent dance music (IDM) is a style of electronic music originating in the early 1990s, defined by idiosyncratic experimentation rather than specific genre constraints. The music often described with the term originally emerged in the early 1990s from the culture and sound palette of styles of electronic dance music such as acid house, ambient techno, Detroit techno and breakbeat; it has been regarded as better suited to home listening than dancing. Prominent artists in the style include Aphex Twin, Autechre, Squarepusher, μ-Ziq, the Black Dog, the Future Sound of London, and Orbital.

The use of the term "intelligent dance music" was likely inspired by the 1992 Warp compilation Artificial Intelligence in 1993 with the formation of the "IDM list", an electronic mailing list which was chartered for the discussion of English artists appearing on the compilation. The term has been widely criticised and dismissed by artists associated with it. Rephlex Records, a label co-created by Aphex Twin, coined the term braindance as an alternative. In 2014, music critic Sasha Frere-Jones observed that the term IDM "is widely reviled but still commonly used".

The origins of IDM date back to the early 1980s with the work of Japanese band Yellow Magic Orchestra (YMO). In 1980, YMO member Ryuichi Sakamoto's solo album B-2 Unit anticipated the sounds of IDM. According to NME, "the entire album eschewed traditional song structures for atmosphere and tone, anticipating the rebellious wave of 1990s IDM" a "full decade beforehand." According to Vice, the B-2 Unit track "E-3A" offered "a hint of the decade to come with its IDM-leaning cut-up complexities." YMO's 1981 album BGM was also a foundation for IDM. According to Analog Planet, the BGM track "Ballet" has an IDM-like electronic soundscape that combines "electronic drums, persistent hi-hats, and sustained synths" with a "melancholic emptiness."

In the late 1980s, ensuing from acid house and early rave party scenes, UK-based groups such as the Orb and the KLF produced ambient house, a genre that fused the pulses of house music, particularly acid house, with ambient music and sample-based soundscapes. By the early 1990s, the increasingly distinct music associated with dance music-oriented experimentation had gained prominence with releases on a variety of mostly UK-based record labels, including Warp (1989), Black Dog Productions (1989), R&S Records (1989), Carl Craig's Planet E, Rising High Records (1991), Richard James's Rephlex Records (1991), Kirk Degiorgio's Applied Rhythmic Technology (1991), Eevo Lute Muzique (1991), General Production Recordings (1989), Soma Quality Recordings (1991), Peacefrog Records (1991), and Metamorphic Recordings (1992).

In 1992, Warp released Artificial Intelligence, the first album in the Artificial Intelligence series. Subtitled "electronic listening music from Warp", the record was a collection of tracks from artists such as Autechre, B12, Black Dog Productions, Aphex Twin and the Orb, under various aliases. This would help establish the ambient techno sound of the early 1990s. Steve Beckett, co-owner of Warp, has said the electronic music that the label was releasing then was targeting a post-club, home-listening audience. Following the success of the Artificial Intelligence series, "intelligent techno" became the favoured term, although ambient—without a qualifying house or techno suffix, but still referring to a hybrid form—was a common synonym.

In the same period (1992–93), other names were also used, such as "art techno", "armchair techno", and "electronica", but all were attempts to describe an emerging offshoot of electronic dance music that was being enjoyed by the "sedentary and stay at home". At the same time, the UK market was saturated with increasingly frenetic breakbeat and sample-laden hardcore techno records that quickly became formulaic. Rave had become a "dirty word", so as an alternative, it was common for London nightclubs to advertise that they were playing "intelligent" or "pure" techno, appealing to a "discerning" crowd that considered the hardcore sound to be too commercial.

In November 1991, the phrase "intelligent techno" appeared on Usenet in reference to English experimental group Coil's The Snow EP. Off the Internet, the same phrase appeared in both the U.S. and UK music press in late 1992, in reference to Jam & Spoon's Tales from a Danceographic Ocean and the music of the Future Sound of London. Another instance of the phrase appeared on Usenet in April 1993 in reference to the Black Dog's album Bytes. And in July 1993, in his review of an ethno-dance compilation for NME, Ben Willmott replaced techno with dance music, writing "...current 'intelligent' dance music owes much more to Eastern mantra-like repetition and neo-ambient instrumentation than the disco era which preceded the advent of acid and techno."

Wider public use of such terms on the Internet came in August 1993, when Alan Parry announced the existence of a new electronic mailing list for discussion of "intelligent" dance music: the "Intelligent Dance Music list", or "IDM List" for short. The first message, sent on 1 August 1993, was entitled "Can Dumb People Enjoy IDM, Too?". A reply from the list server's system administrator and founder of Hyperreal.org Brian Behlendorf, revealed that Parry originally wanted to create a list devoted to discussion of the music on the Rephlex label, but they decided together to expand its charter to include music similar to what was on Rephlex or that was in different genres but which had been made with similar approaches. They picked the word "intelligent" because it had already appeared on Artificial Intelligence and because it connoted being something beyond just music for dancing, while still being open to interpretation.
