Might be a bit of an oxymoron but you know what I mean. I like IDM, although its usually not very "make your booty groovy" type stuff. I was looking for something I could actually move to, while still being considered "IDM" whatever the hell that is.
I understand your intention although I think most of the glitchy drill'n'bass/IDM is danceable - but in a weird way. So I'm not absolutely sure of "how far" you're ready to stretch the danceable limits
this album's really cool, glitchy, and has steady rhythms. Aoki Takamasa's Rhythm Variations
Bogdan Raczynski's Samurai Math Beats has cool straight-forward rhythms, and some cut-up breakbeats too
Lusine ICL has very danceable IDM in his first efforts (Serial Hodgepodge has three of four tracks I would recommend)
