Electrojuice is some hardcore electro, by some danish boys. I'm not too sure if you'll like it, but I think it's worth a listen.
Drifting away by
Lang feat. Skye is nice too. It's the kind of track that starts of kind of "meh", but gets epic later on
What I really think you'll love: the guy by the name
Nitrous Oxide. Check out Amnesia, Orient Express, North pole and especially Show me.
Also, check out
Deadmau5 feat. Kaskade - I remember.
I hope you will like some of it!
