My favourite music these days is glitch, spare electronica between the wimpyness of ambient and the aggro of industrial. Glitch has an electronic sheen but manages to avoid techno's soullessness.
My favourite glitch group is Autechre. Their Tri Repetae++ is brilliant, but it was Chiastic Slide I first noticed. I picked it up cold at a record store because of the beauty of the Designer's Republic cover art.
