IDM and Intelligent Techno are terms for electronic music rooted in Techno and dance music but intended less for the dance floor than for home listening. The “intelligent” tag stems from the Artificial Intelligence compilations, released by Warp in the early 1990s. Related to the slightly broader term “electronica”.
