Be a bit more specific w/ your genres. I know of some good-to-great jungle, hardcore, darkcore, dnb, liquid dnb and breakbeat stuff, and some general techno. The only glitch artists I'm consistent with is Christen Vogel, but some of Luke Vibert's works fall into that as well. Almost none of my picks are obvious choices, tho (underground mostly even by underground standards).
I'm guessing breakcore would be like darkcore but more minimalist, right?
