Another dubstep here. This is a great example how minimalism can make a huge effect. Slow and lazy. Not to much is happening here, yet everything has perfect timing and sounds touch just the right places in your body and mind. And the quote sampled gives it great context and feeling. Very good production is just icing on the cake.
