Madeon

I think it's pretty safe to assume that Madeon is going to be utterly enormous.  He is one funky dude, crafting a tasty blend of electro house and disco sounds.  At a tender 17 years of age (yes I fucking hate him for being so young too, oh well), he's already released remixes for Deadmau5, Pendulum, and The Killers.  He was launched into the spotlight when he won Pendulum's remix contest for The Island, and recently received wide spread interest for his live "Pop Culture" mashup which has racked up over 5 million views on youtube.  He'll be dropping his debut EP of original material sometime in the near future, so keep an ear out.  The preview in this video makes it sound like its going to be killer.
