1. Isn't that bit just a random sample from a Youtube video?
2. I saw Skrillex live last weekend and it was freaking INSANE!

Free concert at the university. I managed to get about 3 rows from the front. I was jumping the whole time and pretty much had the time of my life. He's a surprisingly good performer too, you can tell how much fun he's having and it just adds to energy of the crowd.
And it's not exactly the the most similar sound, but I really enjoy some stuff by http://www.youtube.com/watch?v=hbAUwi4D3Ew. Might want to look at Wolfgang Gartner and and Bassnectar too. Not sure if any of them have enough

(wub wub) for you, kinda more electric than dub, but that's what I've got off the top of my head.
