I honestly don't think electronic has anything to do with the blues because I see no similarities between the two. I'd say electronic music was a way for the Germans to create their "rock" sounds with electronic instruments. And of course, you must mention Stockhausen as a big influence on Kraftwerk. I'd say that Rock was heavily influenced by the Blues, but doubt that electronic has any similarities. I think Reggae/Dub music had some sort of influence on electronica, but nothing that truely shapes it's background.
Are you a big electronica listener, Satch? Hopefully you have a little bit more knowledge with electronic music than Syd did. He's only listened to a handful of the modern electronic artists and pigeonholed it to have no emotion whatsoever....
...then again, we are in a jazz forum, and maybe this isn't the place to be having this discussion
Bottom line, I feel like Blues influenced and shaped what Rock became, and perhaps Electronic music was shaped by Rock, but find that the predecessor really has no influence, in this case to the ending result. Damn, I sound like a math teacher, nevermind, disregard what I just said...
