You can tell that lo-fi dubstep has become too mainstream for hipsters by the way reviews for the really good stuff is directed more toward the middle than the top. Even the likes of James Blake is considered passe in some circles. I blogged about Deptford Goth recently HERE but now his EP is out and you needed to know that. Don't follow those who follow the trends, follow the music.
