English production duo The KLF accomplished a lot in their time, including inventing the kind of willfully dumb, massively popular stadium techno that basically turned into the Mortal Kombat theme — and then taking one million British pounds sterling of their profits and burning it on camera. The relevant album here, though, is 1990's Chill Out, an dreamy collage stitching together samples of preachers, salesmen, Elvis, and other sound-junk with gossamer synthesizers and the very occasional beat. History calls it "ambient house." History overcomplicates things. Really, It's post-sample meditation music — the sound of traveling without having to peel yourself off the couch.
