New vs Old?

Hey guys, first I'd like to say sorry for not posting in a while, I have been busy with irl stuff. Anyways, today's post is going to be about La Roux's song 'In For The Kill', more specifically a certain 2 remixes that have been made. To be honest, I was actually planning to make this a "which is better"-post, but instead it is going to focus more on the difference between older-dubstep and newer-dubstep.
As you can see in the older, Skream remix, the older-dubstep is more focused on sub-bass and the drum pattern.

While we in the Skrillex remix see that the newer dubstep is more focused on the "filthy" and "screamy" sound.

North American dubstep

Hey guys, recently I started thinking, do they listen to dubstep as much in North America as we do in Europe? Seeing as Bassnectar has 500k likes on Facebook and Skrillex has more than 1 million on his facebook while most of the famous UK producers have around 300k, but are more than the NA producers you can say its about the same.
A mate of mine linked me a video of Bassnectar performing live, I didn't think about him being American at the time, but I liked it.
Here's a video of him dropping

DC Breaks -- Halo (Bassnectar remix)

And then we have Skrillex and 12th Planet that you
can see co-operating in this video

Anyways, keep on dubbing all over the world my fellow dubheads!
