I think about this a lot too! The experimental music of that time period was challenging (in a good way) – I’m thinking of people like Keith Fullerton Whitman, SND, Alva Noto, Ryoji Ikeda, Oval, etc. What they were doing was far away from the dance music of the time, although clicks & cuts did marry some ideas of dance music to the experimental stuff.
Imo, the big difference in experimental electronic music these days is that it exists in a much deeper dialogue with dance music. I’m thinking of labels like Hausu Mountain (eg Fire-Toolz, who rules!) and Pan. You can actually hear some weird approximations to dance music in experimental electronic now – eg, Amnesia Scanner makes experimental stuff that you could almost see being played in a club setting. That’s definitely not true of, say, Mego.
