The only ghost I've danced with, was Deadmau5 and Rob Swire's "Ghosts N Stuff" back in 2009. These may be two extremely different tracks, stylistically speaking, but they do however share one similar attribute: the tunes are both really fucking good.
Well, since I have you here, and we're thinking back in time a little bit, let's take a quick trip down memory lane. Do you remember Cazzette's hit track "Sleepless"? It was the tune that was dropped in nearly every main stage festival set. Well, again, these two tunes are stylistically different, but damn, are they amazing.
Chances are the Swedish duo has more tunes coming up, so I recommend you give them a follow on Twitter.
