Rapped vocals are generally a tough sell for me, but I've found myself enjoying some of the "noise-hop" groups that have been popping up in the last few years. This is one such group, but they take the noise component a step further by dialing up the distortion and keeping it at the forefront of the mix. The result is very abrasive and suits the thuggish vocal delivery well. The vocals do ape Death Grips pretty heavily, but the instrumentation is its own beast and is what really sells this.
Favorite track: DROPSHIP.
