Well let's see, going all the way to the godfathers of electronic music, Kraftwerk.. to Front 242, Frontline Assenbly, Skinny Puppy, Download...to things like FSOL, Faithless, Daft Punk (and Stardust, a side project from one of the guys in DP)
Aphex Twin (dont'cha just love the uncensored video for "Windowlicker"?) u-ziq(Michael Paradinas) .. and DJ Paul Oakenfold.. I think that's enough to get started on
