Intelligent dance music (IDM) is a style of electronic music originating in the early 1990s, defined by idiosyncratic experimentation rather than specific genre constraints. It emerged from the culture and sound palette of electronic styles such as ambient techno, acid house, Detroit techno and breakbeat; it has been regarded as better suited to home listening than dancing. Prominent artists associated with it include Aphex Twin, Autechre, Squarepusher, Boards of Canada, Amon Tobin, Higher Intelligence Agency, Telefon Tel Aviv, μ-Ziq, The Black Dog, The Future Sound of London, Mouse on Mars, Biosphere, Orbital and Luke Vibert.
