Rated 6/10
It's the production approach and beat making skills of what's usually consigned to be back-up support in music, taken to the extreme point where the otherwise dominant element of hip hop, rapping, becomes extraneous. This one's been in my regular work-listening rotation for years. Does a good job keeping out other noise, interesting and varied enough to not become annoying, but relaxed and chill enough to not demand attention or take focus.
