Anchorsong is a Japanese producer, but currently based in London. Last November he released "Chapters" via Tru Thoughts, an album containing some nice instrumentals for the Beatheads. The first single "Plum Rain" was already highly successfull in terms of internet buzz.
Another favorite of mine is "Darkrum", that has this kind of worry-free groove on, you want to start the day with... you know, like at around noon on a sunday.
