This is one of the strangest pieces of advice I've heard in a while. If you like "hard dubstep like Skrillex" go listen to two totally different genres.. Doi?
I'm one of those fella's that gets really pissed of when people refer to Skrillex as being Dubstep. Dubstep started out as a mixture between 2-step Garage and Dub music (which is in itself a subgenre of Raggae). Early heroes of the genre are the likes of Benga, Skream, Caspa, Rusko, the DMZ folks. Listen to these artists and then try to tell me that skrillex actually belongsm to the same genre. Just for some chucks and giggles listen to any Skrillex song and compare it to the following:
Dubstep anno 2006

Which by 2008 had turned into

By this time the genre was probably at it's peak, for me personally summarized by Benga's "Diary of an Afro Warrior" (Still a great album IMO) Also, this:

The years following this the genre diversified into several different genre's, leaving a major mark on ather fields of electronic music and even pop music (WTF?!) This is were Skrillex came to the stage in about 2010, popularizing a kind of music that was influenced by Dubstep, but probably equally by Electro, House, Techno and a few other genres.
Dubstep went on to be what it had been but it also spawned new subgenre's such as "Trap" "Future Dub/ Future garage" and the like. A personal favorite of mine at the moment is this:

I'm sorry for trying to force my opinion down your throat, but calling Skrillex Dubstep is like comparing Elvis Presley to Nickelback and claiming Nickelback invented rock n' roll music.
Haha I think I just needed a forum to state my opinion, hope you like the music I posted tho.
