I dunno... a lot of what's been mentioned is sort of dancefloor music. What gets called "glitch breaks" where I come from.
When I think of glitch i usually first think of more experimental stuff like Richard Devine, Mira Calix, Proem, Autechre or Brothomstates. Stuff like that. Definately not something like Bassnectar or SOTEG, that's for sure. Those are just really good breaks. And to me, Volsoc is just electro break stuff. A lot of what they do is analog, and sounds electro.
MachineDrum is probably my favourite doing the glitch-hop thing. I amazed how under the radar he still is in some circles. Pretty tight sounding stuff.
