Hey, Albert. DeepR asked for one piece at a time. It's easy to forget in all the excitement, but I understand the reason.
I've grown to love electronica now that it has more sug-genres than there are stars in the galaxy. I don't care at all for the type of dance music that goes THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP mmm THUMP

, but other stuff is really fun for this older codger who remembers when synths were so new they actually frightened people.
So, though I love glitch, dubstep, ambient and newer stuff I don't even have a name for I'll start with really old school. Though it incorporates a little acoustic piano too, here's what electronica was for us in the 70s. (There are three pieces in the video, but the first one is representative and all I intended.)
[Edit: YT videos are starting to sound harsh and glaringly digital to my ears lately. What have they done? Compressed everything to death?]
Oh - I'm supposed to say why I like it. It's one of the first pieces I ever heard using completely synthesized percussion. I'm sure it's not THE first. Just the first I heard., and I have fond memories of hearing it surrounded by black light posters in a haze of incense and other smolderings. Also I think it's in 6/8? which is a little unusual for any kind of non-classical. No - I think it's polyrhythmic. Or maybe just 4/4 with triplets or different accents. Okay, I give up.
