The 'intelligent'/'pure' techno framing arose as a taste distinction against commercial hardcore rave
The ‘intelligent’ framing that seeded IDM was, at root, a social distinction. In the early 1990s the UK market was saturated with increasingly frenetic, sample-laden hardcore techno that quickly became formulaic, and ‘rave’ had become a ‘dirty word’. As an alternative, London nightclubs began advertising ‘intelligent’ or ‘pure’ techno to appeal to a ‘discerning’ crowd that considered the hardcore sound too commercial. So the term encodes a value judgement — separating a supposedly cerebral, tasteful strand from the mass-market dancefloor — which is exactly what later made ‘intelligent dance music’ controversial. Understanding this origin explains the label’s baggage: it was a marketing/taste boundary before it was ever a genre description.
Examples
Period synonyms ‘art techno’ and ‘armchair techno’ carried the same distinction-making function. Clubs billing ‘intelligent’ or ‘pure’ techno signalled a crowd defining itself against commercial hardcore rave.
Assessment
Explain what social/market conditions produced the ‘intelligent’/‘pure’ techno framing, and why that origin makes the ‘intelligent’ label controversial.
