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.
