He investigates and innovates. And when he's not trying to sell his craft to 15 year old drunkards who only care about jumping up and down, he creates wonderful pieces. And even some of those can be fixed by taking out a single sample (such as Equinox, which would be perfect if only he hadn't put the "Call 911 Now" scream).
Personally, I'll never get tired of Scary Monsters and Nice Sprites, Rock and Roll (will take you to the mountain), Summit or Recess, to name a few. I agree that Recess might be the less intended to just listen and enjoy and that's why I put it as example.
Summit, on the other hand, is official sound track for introspective night walks.
