This song is fantastic, one of the most unique dubstep tracks I've heard in a while. All of the crazy rhythms in this somehow manage to work together without sounding disorganized. The bass design is stellar, the melodies are perfect, and alltogether it is very polished.
If I were to say anything negative about this track, its that the drums could be mixed better. In the verses the snare isn't as present as it could be, and the low end is a tad muddy, but other than that this track is perfection!
