I’m not usually a fan of dubstep, it doesn’t seem to push the point of a song forward at all. Most producers get caught up in their own hubris, creating a pointless reiteration of the wubba-wubba sound.
However, I’m a fan of DJ Ants’ work, so I gave this a listen. He does a brilliant job of making the melody important and a driving force to the song. Worth a listen, the download is available on his soundcloud page.
