Gary Clark Jr is, at his roots, a straight-ahead bluesman. He's not afraid of a single chord groove and feels very much like a John Lee Hooker of this day and age. He's a master of blues groove and fuzzy lead guitar too, so plenty to learn.
This track is all based around a simple bluesy groove, some epic fuzz tones, and pentatonic blues riffing. Of course, when you have the kind of feel and style Gary Clark Jr has, you really don't need anything more!
