O F F Is Well Loved

Who is O F F Love? Why is he here? What is he about? All we know is that a) it IS a 'he' ( the yin/yang masked covering he purveys in live outings gives nothing else away) b) he has opened for the likes of Kindness and How To Dress Well c) he is minimalist to the point of extreme d) once heard/seen, you're not likely to forget in a hurry.
